Lenses, lens adjustment methods and electronic equipment
Abstract
This application provides a lens, a lens adjustment method and an electronic device for projecting multi-frame image display signals on a screen. The lens includes an optical engine, a deformable prism and a processor. The optical engine includes multiple point light sources. Each point light source The light emitted at the same time can form a first pixel point on the screen, and multiple first pixel points constitute the Nth frame image display signal; the deformable prism sets the light exit surface of the light engine; the processor, the processor and the light engine respectively The deformable prism is electrically connected, and the processor is used to: control the light machine to form the Nth frame image display signal on the screen; control the deformable prism to be in a first bending state to form a plurality of second pixel points on the screen, and a plurality of second pixels. The pixels constitute the N+1th frame image display signal, and each second pixel is used to fill the gap between adjacent first pixels. Adding a deformable lens to the lens increases the number of pixels per inch of the screen, making the display smoother and achieving higher clarity.


Technical field

The present application relates to the technical field of wearable devices, and in particular, to a lens, a lens adjustment method, and an electronic device.

Background technique

In the use of AR (augmented reality, augmented reality) glasses, the current glasses need to light up the waveguide lenses, which all use optical machines for screen projection. As a part of glasses, the size and weight of the optical machine play an important role on the eyes. The smaller and lighter the optical machine is, the closer it can be to real glasses, and the pair will be more comfortable to wear. However, if the optical machine is too small, it will inevitably require a very high PPI (pixel per inch) to reduce graininess when displayed under a large FOV (Field of view). Existing micro LED (micro LightEmitting Diode Display) mass-produced displays can only achieve a 4 μm pixel gap, achieving a display of 640 times 480 on a 0.13-inch (inch) display. resolution. Applying existing microLEDs to optical machines, the projection distance of the optical machine reaches more than 2m. When FOV>40°, the diagonal resolution on the screen is only 16~20DPI (dots per inch, pixels per inch). Therefore, users will see uneven and grainy textures when using AR glasses.

DEVICE FOR MONITORING AN EYE POSITION OF A USER’S EYE IN A VIRTUAL RETINAL DISPLAY, DATA GLASSES, AND METHOD
Abstract
A device for monitoring an eye position of a user's eye in a virtual retinal display. The device includes a laser projector unit generating a collimated scanned infrared laser beam, and an optical system optically guiding the scanned infrared laser beam to the user's eye. The optical system includes an optical element for the scanned infrared laser beam to pass through, or diverting the scanned infrared laser beam. The optical element forms a region in which the collimation of the infrared laser beam is maintained, to generate a bright pupil effect and/or a retina speckle pattern. The optical element forms a second region in which the infrared laser beam is focused on an iris of the user's eye, a center of the user's eye, or a cornea of the user's eye, to generate a glint.


It is further proposed that the optical element is designed as a multifocal lens or varifocal lens. This makes it possible to advantageously switch between different beam shapes of the infrared laser beam. Advantageously, a cost-effective, compact and/or energy-saving determination of the eye position and/or the gaze vector can be made possible with just a single infrared laser beam. The multifocal lens or varifocal lens particularly forms the temporal areas. The multifocal lens or varifocal lens can in particular be segmented into the two spatial areas. However, the spatial areas on the multifocal lens or varifocal lens preferably overlap, preferably even completely. Consequently, the multifocal lens or varifocal lens, in particular during operation of the device, switches actively and repeatedly and continuously at least between the optical functions of the first (temporal) region (collimation of the infrared laser beam or maintaining the collimation of the infrared laser beam) and the (temporal) second area (focusing the infrared laser beam) and possibly also the third (temporal) area (focusing the infrared laser beam on a further focus point). In particular, the multifocal lens or varifocal lens is designed as an electronically controllable lens. In particular, the multifocal lens or varifocal lens is arranged in a beam path of the virtual retinal display between the scanner (MEMS micromirror) and the HOE (lens of the data glasses). For example, the multifocal lens or varifocal lens could be called a TLens® from poLight® (Skoppum, Norway). Alternatively, an Alvarez lens, a diffractive retardation plate or another electrically controllable or movable lens could replace the multifocal lens or varifocal lens.

The liquid lens micro-projection device includes: a display component for displaying images; a projection lens arranged on one side of the display component, and the projection lens is The image on the display component is enlarged and projected; a liquid lens component is disposed on the side of the projection lens away from the display component, and the liquid lens component is used to generate deformation and change the optical path to achieve micro-projection focusing. Function. The liquid lens micro-projection device and electronic equipment provided by the present invention can change the optical path to adjust the focal length by changing the shape of the liquid lens, and are smaller in size and simpler in structure.


Technical field

The invention relates to the technical field of projection equipment, and further relates to a liquid lens micro-projection device and electronic equipment.

Background technique

The main working principle of the projector is to emit light from a light source, and through a series of optical lighting systems, the light from the light source is evenly illuminated on the display chip, and the signal is realized on the display chip through the circuit system to achieve color and gray levels, displaying The image is then enlarged and projected onto the corresponding screen by the projection lens at the front end of the projection.

At present, micro-projection technology is becoming more and more common in electronic products. However, existing projection lenses are usually larger in size. Correspondingly, in order to achieve the focusing function, the driving mechanism of the lens requires a larger drive, so the corresponding voice coil motor size is also relatively large. big. Existing micro-projection devices have complex structures, high costs, and large volumes. The lens modules required by smart devices are relatively small, making it difficult for traditional micro-projection devices to be applied to electronic devices.

Therefore, it is necessary to design a liquid lens micro-projection device to solve the above problems.

In view of the above technical problems, the purpose of the present invention is to provide a liquid lens micro-projection device and electronic equipment that can change the optical path to adjust the focal length by changing the shape of the liquid lens, and has a smaller volume and a simpler structure.

In order to achieve the above object, the present invention provides a liquid lens micro-projection device, including:

Display component, used to display images;

A projection lens, arranged on one side of the display component, the projection lens is used to amplify and project the image on the display component;

A liquid lens assembly is provided on the side of the projection lens away from the display assembly. The liquid lens assembly is used to generate deformation and change the light path to achieve the function of micro-projection focusing.

In some embodiments, the liquid lens assembly includes a base, a liquid lens disposed on the base, a pressing member, and a driving mechanism. The driving mechanism is connected to the pressing member, and the driving mechanism can drive the pressing member. Pressing the liquid lens causes deformation to change the light path to achieve the micro-projection focusing function.

In some embodiments, the liquid lens can deform, and during the deformation process of the liquid lens, the liquid lens can focus, the pressing member is a piezoelectric element, and the piezoelectric element is arranged adjacent to the liquid lens, The driving mechanism includes a power terminal connected to the piezoelectric element. When the power terminal applies a voltage to the piezoelectric element, the piezoelectric element deforms, and the piezoelectric element deforms. The deformation of the piezoelectric element drives the deformation of the liquid lens, thereby changing the optical path to achieve the micro-projection focusing function.

Jeg tenker tilbake på telefonen som ble kansellert i 2021 når det der spm kommer🙂

Jeg tenker isåfall at PLT har en "muntlig" avtale med APPLE som går under samme type avtale som da🙂 Vi fikk aldri noe PO ordre mot den som ble kansellert i 2021, Den visste vi bare om i etterkant da Øyvind og Co hadde fått til en betaling, En slik etterbetaling på over 3 mill er jo egentlig børssensitiv🙂👍

Ok takk for svar kraamz. Tenker bare at hvis vi er i Apple Pro Vision , så må jo produksjonen av produktet snart være ferdig, og hvis da brillen inneholder Tlens så skulle en tro at Apple kjørte en bestilling mot polight for flere måneder siden ?

XR-3 var kjent som DEN beste ifølge flere. Denne nye tar et steg videre og muliggjør enda flere ting samt har bedre hardware generelt. Hvordan de evt gjør det mtp en PO mot Apple kan vi bare spekulere i men det er nok som du skriver, Meget sansynlig at en større PO kan komme snart🙂. Vi får vente i spenning 🙂

Vanvittig bra med Varjo XR-4, men et par ting jeg lurer på! Varjo XR-3 er uten tlens, det får vel også gode tilbakemeldinger? En annen ting, om vi skulle vært i Apple som lansere sin briller nå i desember, burde vi ikke hatt en større PO for lenge siden her? Ryktes jo at denne blir en masseproduksjon sak, burde vel uansett hatt en PO med litt størrelse??

Polight deltar på Spie🙂

https://spie.org/conferences-and-exhibitions/ar-vr-mr/exhibition/for-exhibitors?SSO=1

Det var jo akkurat det som var argumentet i forrige emisjon, men nå skal vi altså ha en ny for samme opplegget, ny i 2026 også da kanskje? Utvanning etter utvanning, spiser opp den supre gevinsten småsparerene hadde sitt for seg. Tipper at vi til slutt ender på 200 mill aksjer som tilsvarer en markedsverdien på 2 mrd ved 10kr i kurs, da skal det jaggu selges vilt med linser…

Det blir behov for Emisjon, Det er nok bare snakk om tid desverre, Det koster å gå inn i utvikling av TWedge samt gjøre organisasjonen klar for alle disse AR casene som kommer i 25-26 osv.

Det tar tid å få igang ny tech når det er en incumbent(VCM) som har så og si hele markedet, dette ser vi med alle Liquid-lenses, PoLight har faktisk en ganske god andel sett oppimot all konkurranse mot VCM, det blir bedre og bedre men TTT 🙂

Ja å innen den tid er jeg redd noe annet fantastisk dukker opp fra sidelinjen.. En annen ting er jo en ny emisjon om dette drar ut til 2025🥺

Jeg tror nok Elabs tar fart no etter å ha fått masse innpass i laptops, det er der pengene er for Elabs🙂 Smartphone er veldig lav enhetspris på for Elabs.

For PLT er man oppe i 14-20kr pr TLens i mobil med rundt 20% Fortjeneste, Da kan en stykk High volum model utgjøre store summer for PLT 🙂 Jeg tror dog vi må ut i 24-25 Før dette kan ta av🤞🙂

Blir nok ikke til at jeg selger før høsten 24, må gi det noen mnd til… Se på ELABS som er inne i haugevis av produkter, ordrer og nyheter nesten ukentlig, likevel blir det dårlige resulterer q etter q og en aksjekurs som ikke imponerer! Hvorfor mener du at polight vil bli annerledes?

Kan godt forstå om folk er lei av ventingen, Har gått lengre tid å komme inn i høy-volum enn vi hadde tenkt😔 Vi krysser fingrene på at AVP vil dukke opp med TLens over nyåret slik at alle kan se at TOP produkter velger TLens av en grunn og ikke minst at det er verdt den ekstra kostnaden. Må opp i volumordrer for å få ned pris på modulene med Tlens.

Lykke til med valget🙂👍

Hei,

Fin oversikt og en imponerende liste over produktene som inneholder T-lens, men inntektene uteblir, innsidehandlene er totalt fraværende, ja de har nok et aksjespareprogram, men synes fortsatt det er rart at ingen handler! Med så mange produkter, burde det vist igjen på bunnlinjen!

Har 50K polightaksjer selv, stooort tap som jeg vurderer å realisere! Begynner å bli smålei dessverre😏

Flott oversikt delt av Aandal Vanger🙂🙏

Head-mounted display system with display and adjustable optical components
Abstract
An electronic device such as a head-mounted display or other display system may have a transparent display. The transparent display may be formed from a transparent display panel or a display device that provides images to a transparent optical coupler. A user may view real-world objects through the transparent display. Control circuitry can direct the transparent display to display computer-generated content over selected portions of the real-world objects. The head-mounted display may have adjustable components through which the user may view the real-world objects. The adjustable components may include an adjustable light modulator, an adjustable color filter, and an adjustable polarizer. The control circuitry may adjust these components based on information from a front-facing camera that captures images of the real-world objects, based on information from a gaze tracking camera, and based on other input.

[0031] Tunable lenses 54 may be liquid crystal tunable lenses, tunable lenses based on electrooptic materials, tunable liquid lenses, microelectromechanical systems (MEMS) tunable lenses, or other tunable lenses.

0037] Cameras such as front-facing camera(s) 64 may be used to capture images of the real-world environment surrounding the user. For example, one or more front-facing cameras 64 may be used to capture images of real-world objects in front of a user and on the left and right sides of a user's field of view. The images of real-world objects that are gathered in this way may be presented for the user on display 26 and/or may be processed by control circuitry 50 to determine the locations of electronic devices (e.g., displays, etc.), people, buildings, and other real-world objects relative to the user. The real-world environment may also be analyzed using image processing algorithms. Information from camera 64 may be used in adjusting optical components and controlling display 26 .

0043] Components such as components 40 may be supported by support structures 16 adjacent to user's eyes 12 . Components 40 may include gaze detection cameras 62 (image sensors) and/or other sensors for detecting the direction of the user's gaze. Components 42 may include speakers (e.g., ear speakers) or other audio components 72 that play audio (e.g., audio associated with computer-generated images and/or other content that is being displayed using display 26 , etc.). Components 42 may be mounted adjacent to the ears of a user.

[0044] Components such as components 18 and 28 may be optical systems (e.g., collections of one or more fixed and/or tunable lenses) and/or may include clear transparent members (e.g., protective layers). The lenses in optical systems 18 and 28 may be used to focus light from display 26 and/or light from real-world objects 30 and 32 that is passing through components 20 , 22 , and 24 before this light reaches the user's eyes 12 .

Polymer lenses
Polymer lenses (as used by RGB cameras1) are mounted on the front of HMDs to capture and display real-world images of one's surroundings, or to show the real-world surroundings like a window layered over a portion of the VR world.
These are ultra high-speed autofocus lenses consisting of an optical-polymer lens core and piezo actuator. To control the lens focal length, an electric voltage is applied to the actuator to deform the lens core shape. Autofocusing by conventional lenses involves a voice coil motor (VCM), which moves the lens relative to the image sensor. High-speed, high-precision movement is required so that the unit can quickly adjust and keep images in focus. This makes sharp and accurate image capture difficult. Polymer lenses can eliminate this shortcoming. These lenses simply change the shape of the element consisting of optical polymer to quickly focus on objects at different working distances or at different heights. Actual autofocusing is extremely fast, at 1 ms. This is about 10 times faster than lenses with a VCM.
What's more, unlike lenses with a VCM, polymer lenses do not alter the angle of view (the image area shown) even if the focal position moves - a great advantage in preventing an HMD issue called VR sickness. This makes polymer lenses ideal for applications that require high-speed focusing or transmission, as well as applications requiring an adjustable depth of field or working distance.

The current examination method for oral cancer mainly relies on histopathological biopsy. However, on the one hand, biopsy is prone to false negatives due to sample size issues; on the other hand, biopsy is an invasive operation. Therefore, it is necessary to develop a non-invasive, all-round, high-resolution method. Oral cancer screening method to achieve early detection and treatment of oral cancer.

As an emerging biomedical imaging method, OCT imaging technology can achieve micron-level resolution at millimeter-level imaging depth compared with traditional optical imaging technology. Based on the basic principle of weak coherent light interference, during the OCT imaging process, When near-infrared weak coherent light irradiates the imaging area, the tissue signal light of the sample arm interferes with the reference light of the reference arm. High-resolution three-dimensional morphological structure information of biological tissues can be obtained through scanning. However, most current imaging based on OCT The focal length of the excitation beam of the device is fixed, and the focus of the spot cannot be adjusted in real time according to the morphological changes of the sample. This usually results in defocusing of the focus of the beam and image distortion.

The Chinese patent application number is 202010020276.1, and the patent is called "Self-focusing OCT endoscope with variable working distance". It discloses a self-focusing OCT endoscope with variable working distance. This invention uses the close range of the OCT itself to transmit and receive. The infrared laser signal is used as the basis for adjusting the working distance of the endoscope to achieve self-focusing OCT imaging with variable working distance; however, the focusing element used in this method is a liquid lens, which is prone to leakage, is affected by gravity, and uses magnetic Electromagnetic interference will be generated when driving, the response speed is slow, the volume is large, and the driving voltage is too high. In addition, when the patented endoscopic probe performs circular scanning, the internal component layout will interfere with the beam scanning area, thus affecting the imaging. quality.

In view of the above-mentioned deficiencies in the prior art, the object of the present invention is to provide a variable-focus OCT capsule intraoral imaging device, which can be used to realize real-time focus adjustment of the excitation beam during the OCT endoscopic imaging process, so as to avoid damage to the surface of the oral tissue. Problems such as image distortion caused by spot defocus caused by irregularities and unevenness.

In order to achieve the above object, the present invention provides a variable focus OCT capsule intraoral imaging device, which is characterized in that: it includes a capsule housing and an optical element combination for OCT imaging provided in the capsule housing, along the propagation direction of the optical path, The optical element combination sequentially includes a single-mode optical fiber arranged on the same optical axis, a collimating lens, an achromatic lens, a beam expander lens, an all-solid-state variable focus element based on piezoelectric drive, and a reflector. The OCT excitation input by the single-mode optical fiber The light is collimated by the collimating lens to form first collimated light. The first collimated light is expanded to form second collimated light after passing through the achromatic lens and the beam expander lens. The second collimated light is After being focused by the all-solid-state variable focus element based on piezoelectric driving, the mirror is focused on the sample outside the capsule housing;

The all-solid-state variable focus element based on piezoelectric drive is electrically connected to a second cable extending from the outside of the capsule housing, and is driven by the second cable to change the curvature radius of the surface of the all-solid-state variable focus element based on piezoelectric drive, Used to change the focus depth of OCT excitation light.

Kjedelig med dette papirtapet😢 Jeg tror derimot kurs vil bedre seg utover mot starten av 2024 pga mange nye produkter av verdi👍 Er vi i AVP blir det fest🤞☺️. Lurt å sette av litt av porteføljen til å forberede mot en EMi, Det kommer jeg til å gjøre🙂👍

Frykter at polight kommer litt vel sent til de store inntektene, det blir ikke lenge inn i 2024 før pengebehovet vil melde seg, altså ny emisjon! Nok en ny utvanning, da begynner interessen å falle for min del. Har et stort tap på papiret i dag, håper selvsagt dette snur, men tviler🥺

Polight Asa nevnt som en av Top companies innen utvikling for medisinske endoskop🙂👍
