Nytt patent fra poLight. Kalibrering av strøm/linse regelmessig for å ha samme optiske styrke uansett tempetatur.

Men, se denne:
0076] The optical powers OP1, OP2 may be determined in various ways. For example, a user determined or predetermined distance between a screen placed in front of the camera module 150 and the camera module gives the first optical power OP1, and the first voltage V1 is the voltage which provides a focused image of the screen. The second voltage V2 and optical power OP could be determined similarly based on another distance to the screen. Alternatively, the second optical power OP2 may be the optical power which provides focusing at infinity and the second voltage is the voltage which provides focus at infinity, e.g. a relative large distance such as 10m.

Dette er et patent som dekker mer enn kameramoduler. Også laserapplikasjoner dekkes, +++

Det bygger på seg for poLight sin segmentportefølje her Myrabakk, veldig spennende. I disse dager er jeg umåtelig spent på hva neste børsmelding vil inneholde. Tenker det vil gi ytterligere fart på aksjekursen. Vi ser allerede et innrykk av utenlandske investorer på eiersiden i poLight og personlig mener jeg at det vil eskalere fremover. Fra serien Utvandrere "far du må vakna, indianarane kjem !".

Apple AR-briller
Har ikke sett dette patentet tidligere. Tunable lens i AR-briller, og både piezoelectric og MEMS nevnes som løsning:

0078] FIG. 17 shows another embodiment for camera module 64. In FIG. 17, the camera module includes a deformable lens. As shown in FIG. 17, image sensor 102 and lens 128 are formed in housing 100 of camera module 64. Lens 128 is a deformable lens (sometimes referred to as a shape-changing lens or adaptable lens). Lens 128 may be controlled (e.g., by equipment 106) to take a desired shape. For example, lens 128 may change between a first shape 129 A and a second shape 129B. The different shapes of lens 128 may each have a different profile of angular resolution while maintaining the same focus. This way, the captured scene may be focused onto image sensor 102 (regardless of the shape of the lens). However, the different shapes of the deformable lens may allow different portions of the captured scene to be magnified (for high-resolution image data). For example, when the lens has shape 129A a portion 130A of the lens may magnify a first portion of the incoming light (e.g., increase the angular resolution of the light relative to surrounding lens portions). When the lens has shape 129B a portion 13 OB of the lens (that is different than portion 130A) may magnify a second, different portion of the incoming light. In this way, the shape of the lens may be controlled to select a portion of the incoming light to optically stretch . Therefore, the shape of the lens may be controlled to obtain high-resolution image data of a selected portion of the captured scene. The lens may be changed between any desired number of shapes (e.g., two, three, four, more than four, more than ten, less than twenty, etc.), with each shape having an associated resolution of image data obtained by image sensor 102.

[0079] Lens 128 may be formed in any desired manner that allows the lens to change shape. For example, the lens may be a liquid lens that changes shape based on liquid volume. The lens may be a liquid crystal lens that changes shape based on a voltage. The lens may include microelectromechanical systems (MEMS) if desired.

Liquid crystal lens er ikke Tlens, men en linse som baserer seg på MEMS kan veldig godt være Tlens😉
Andre steder i patentet er piezo nevnt som valg til styring av linse.

Uansett linsetype som velges her; VCM er ikke et alternativ! I AR ser det nå ut som absolutt alle velger bort VCM. Dette som vi nå ser innen AR er de klareste tegn på et paradigmeskifte jeg har sett, lg dette skjer fort! Dagens consumerløsning innen imaging skrotes fullstendig når nye markeder startes opp. Det er et så vanvittig sterkt signal på hva vi har i vente de neste årene. Tlens kommer ikke til å ta alt. Det sier seg selv at det må være konkurranse. Isaksen selv bekreftet dette på Q4, da han sier at flere aktører ikke vurderer tunable lenses om det ikke er konkurranse. Men poLight er en så sterk og anerkjent aktør innen tunable lenses nå at, og har sterke støttespillere i STM, så de vil garantert få nok å henge fingrene i fremover.

Problemet som skal løses er velkjent for oss:

0003] The advent of small, mobile multipurpose devices such as smartphones and tablet or pad devices has resulted in a need for high-resolution, small form factor cameras for integration in the devices. However, due to limitations of conventional camera technology, conventional small cameras used in such devices tend to capture images at lower resolutions and/or with lower image quality than can be achieved with larger, higher quality cameras. Achieving higher resolution with small package size cameras generally requires use of a photosensor with small pixel size and a good, compact imaging lens system. Advances in technology have achieved reduction of the pixel size in photosensors. However, as photosensors become more compact and powerful, demand for compact imaging lens system with improved imaging quality performance has increased.

[0004] Some small form factor cameras may incorporate an autofocus (AF) mechanism whereby the object focal distance can be adjusted to focus an object plane or field in front of the camera at an image plane to be captured by an image sensor (also referred to herein as a photosensor). In some such autofocus mechanisms, the optical lens is moved as a single rigid body along the optical axis (referred to as the Z axis) of the camera to refocus the camera. In addition, high image quality is easier to achieve in small form factor cameras if lens motion along the optical axis is accompanied by minimal parasitic motion, e.g., tilt around the X and Y axes

Ja dette er uhyre spennende! Ser at det kommet noen kommentarer og spørsmål til artikkelen om potensielle begrensninger knyttet til liquid lenses på noen viktige områder ved bruk i smartphone. En Jim Sterhell svarte i dag;

«A liquid lens will work well with a curved sensor, allowing zooming. Curved sensors offer huge advantages-no need for aspherical lenses-can use spherical lenses, no need for additional elements for flatness of field, fewer elements, corner to corner sharpness, no need to stop down for better images, ability to make the sensor oversized and have the algorithm compensate for shake and focus issues-may be able to add depth of field among other advantages.
Once the technology for curved sensors and a couple of liquid lenses is perfected, all our old gear will become expensive door stops. The sky will be the limit with curved sensors and liquid lenses»

Dette er vel slik jeg har forstått løst i den nye MOU linsen fra PoLight? Som lite fagkyndig selv hadde det vært fint å få noen betraktninger på dette😉

Utdrag:

Recently, the shape of the lens is deformed according to the application of current, and thus, the development of a liquid lens that performs an auto focus function or a camera shake correction function has been made. Accordingly, in a camera device equipped with a liquid lens, there is a need for a conductive pattern structure for energizing the liquid lens.

Furthermore, there is a growing demand for size reduction in a camera device equipped with a liquid lens.

The first embodiment of the present invention is to provide a camera device including a conductive pattern structure electrically connecting a liquid lens and a printed circuit board.

In particular, it is intended to provide a camera device having a high degree of design freedom of a conductive pattern even when the number of electrodes of a liquid lens increases.

A second embodiment of the present invention is to provide a camera device whose size in a direction perpendicular to an optical axis is minimized.

A camera device according to a first embodiment of the present invention includes a holder; A lens holder coupled to the holder; A variable lens unit disposed on the lens holder; And a holder terminal disposed on the holder, wherein the holder terminal includes a first region disposed on an upper surface of the holder and electrically connected to the variable lens unit, and the variable lens unit is disposed in a direction perpendicular to an optical axis. It may not overlap with the holder.

The variable lens unit may include at least one of a liquid lens, a polymer lens, a liquid crystal lens, a voice coil motor (VCM) actuator, a shape memory alloy (SMA) actuator, and a micro electro mechanical systems (MEMS) actuator.

The polymer lens can change the focus by controlling the polymer material through a driving unit such as a piezo. The liquid crystal lens can change the focus by controlling the liquid crystal by electromagnetic force. The VCM actuator may change a focus by moving a solid lens or a lens assembly including a solid lens through an electromagnetic force between a magnet and a coil. The SMA actuator can change the focus by moving a solid lens or a lens assembly including a solid lens using a shape memory alloy. The MEMS actuator may change a focus by moving a solid lens or a lens assembly including a solid lens through an electrostatic force generated when voltage is applied.

FIELD OF VIEW EXPANDING SYSTEM

Light engine 114 may be any sort of device capable of emitting light sources, such as one or more light emitting diodes or laser diodes. Optical system 110 may also include a display engine 116 for consolidating light waves generated by light engine 114 and directing the light waves as appropriate. In one implementation, display engine 116 may be a micromechanical system (MEMS)-based scanning system that can “paint” an image based on light waves produced by light engine 114 .

0039] FIG. 6 depicts the processing of an image by NED device 100 according to one implementation. An optical assembly 602 , such as a MEMS mirror-based display engine, may generate an image 604 that is to be transmitted via a waveguide 606 such that the image may be propagated to a user's eye 608 . In some implementations, waveguide 606 may be of a low index transmissive substrate, such as glass, that may be limited in its ability to guide certain light waves according to TIR.

Another example can include any of the above and/or below examples where wherein the transmissive substrate is a glass or polymer.

Actively tunable optical element with full or partial transparency

0062] An optical element may include one or more electroactive materials, such as electroactive polymers or ceramics and may also include additional components. As used herein, “electroactive materials” may, in some examples, refer to materials that exhibit a change in size or shape when stimulated by an electric field. In some embodiments, an electroactive material may include a deformable polymer or ceramic

0063] For piezoelectric polymers like PVDF homopolymer, the piezoelectric response may be tuned by altering the crystalline content and the crystalline orientation within the polymer matrix, e.g., by uniaxial or biaxial stretching, optionally followed by poling. The origin of piezoelectricity in PVDF homopolymer is believed to be the β-phase crystallite polymorph, which is the most electrically active and polar of the PVDF phases.
