    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.

    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 can 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 can 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 liquid crystal lens employing a dual frequency liquid crystal material exhibiting a dielectric anisotropy about a crossover frequency at room temperature is provided. A tunable liquid crystal lens drive signal having low and high frequency components about the crossover frequency, applies a spatially modulated electric field to the dual frequency liquid crystal layer, wherein the differential root means square amplitude determines the optical power. Changing the differential root means square amplitude provides optical power changes under prevailing excitation conditions providing improvements in optical power change speed. Employing drive signal pulses can impart further optical power change speed improvements. A variety of tunable liquid crystal lens structures employing the proposed solution are described.

    摘要： A variable optical device for controlling the propagation of light has a liquid crystal layer (1), electrodes (4) arranged to generate an electric field acting on the liquid crystal layer, and an electric field modulation layer (3,71) arranged between the electrodes and adjacent the liquid crystal layer for spatially modulating said electric field in a manner to control the propagation of light passing through said optical device. The electric field modulation layer has either an optical index of refraction that is essentially spatially uniform, or a polar liquid or gel, or a very high low frequency dielectric constant material having a dielectric constant greater than 20, and preferably greater than 1000. The modulation layer can have a solid body having a first low frequency dielectric constant with a shape selected to impart a desired modulation of the electric field, and a second low frequency dielectric constant material surrounding or adjacent to the solid body such that the solid body and the second material form a layer geometry.

    摘要： A tunable optical imaging system uses a fixed lens and a tunable liquid crystal lens that is operated only outside of an operational range of high aberration. A voltage range applied to change the optical power of the liquid crystal lens is limited to a continuous tunable range of low aberration. The relative positioning between the lens and a corresponding photodetector, and the relative lens powers of a fixed lens and the tunable lens, may be selected to compensate for any optical power offsets resulting from the limitation of the voltage range of the tunable lens. The lens may be operated in either positive tunability or negative tunability mode.
