摘要： An auto-focus system employing a tunable liquid crystal lens is provided that collects images at different optical power values as the liquid crystal molecules are excited between a ground state and a maximum optical power state tracking image focus scores. An image is acquired at a desired optical power value less than maximum optical power established with the liquid crystal molecules closer a fully excited state than the maximum optical power state having the same image focus score. This drive signal employed during image acquisition uses more power than was used to achieve the same optical power value during the auto-focus scan, while actively driving the liquid crystal molecules is fast. A pause due to image transfer/processing delays after acquisition is employed to allow slow relaxation of the liquid crystal molecules back to the ground state in preparation for a subsequent focus search.
摘要翻译：提供了一种采用可调式液晶透镜的自动对焦系统，其在基态和最大光功率状态跟踪图像焦点得分之间激发液晶分子时，以不同的光功率值收集图像。以比具有相同图像焦点得分的最大光功率状态更接近完全激发状态的液晶分子建立的小于最大光焦度的期望光功率值获取图像。在自动对焦扫描期间采用的这种驱动信号比用于实现相同的光功率值的功率更多，同时主动驱动液晶分子是快速的。采用采集后由于图像转移/处理延迟而产生的暂停，以允许液晶分子缓慢松弛回到基态，以备随后的聚焦搜索。

摘要： Variable liquid crystal devices for controlling the propagation of light through a liquid crystal layer use a frequency dependent material to dynamically reconfigure effective electrode structures in the device. The frequency of a drive signal that generates an electric field in the device may be varied, and the frequency dependent material has different charge mobilities for the different frequencies. At a low charge mobility, the frequency dependent material has little effect on the existing electrode structures. However, at a high charge mobility, the frequency dependent material appears as an extension of the fixed electrodes, and may be used to change the effective electrode structure and, thereby, the spatial profile of the electric field. This, in turn, changes the optical properties of the liquid crystal, thus allowing the optical device to be frequency controllable.

摘要： A tunable-focusing liquid crystal lens (TLCL) cell has a liquid crystal layer arranged within a cell gap defined between substrates, a layer of optically transparent material arranged between the first substrate and the LC layer, and a liquid crystal alignment layer arranged between the optically transparent layer and the LC layer. The alignment layer is provided on a third optically transparent substrate having a non-planar shape for giving a non-planar profile to the LC layer, which substrate is obtained from a flexible sheet initially provided with the alignment layer and then formed into the non-planar shape. The lens further has a first optically transparent electrode provided on the second substrate, a second optically transparent electrode provided on either or both of first and third substrates. The electrodes are arranged to generate an electric field acting on the LC layer to change the focal distance of the LC cell. Methods for fabricating such TLCL cell are also provided.

摘要： A wafer level method of manufacturing a liquid crystal optical device removes the need for a rigid barrier fillet while minimizing any risk of contamination of the liquid crystal. An uncured adhesive may be deposited on a bottom substrate and partially cured to form a liquid crystal barrier. After addition of the liquid crystal and a top substrate, the adhesive is fully cured to bond the substrate layers together. An uncured adhesive may be used together with the partially cured adhesive, and may be deposited separately or filled into an extracellular matrix surrounding a plurality of liquid crystal cells. The adhesive may be cured by a variety of means, including light that may be spatially modulated. One or both of the substrates may be deformed during assembly so as to create a structure with a lensing effect on light passing through the liquid crystal region.

摘要： Methods are provided for wafer scale manufacturing camera modules without adjustment components to compensate for assembly errors and optical errors incurred within manufacturing tolerances. Camera modules are assembled in wafer arrays from arrays of image sensors, arrays of lens structures and arrays of optical trim elements. At least one of the arrays is a wafer. Lens structures are configured to provide less optical power than necessary to focus an image at infinity on image sensors without trim elements. A test performed during the wafer scale assembly of camera modules, after at least the sensor array and the lens structure array assembled, determines optical errors by identifying optical distortions and aberrations quantified in terms of optical power, astigmatism, coma, optical axis shift and optical axis reorientation deficiencies. Corresponding trim elements are configured to counteract distortions and aberrations prior to singulating useful camera modules from the array.
