    摘要: A variable focus liquid crystal lens includes a nematic liquid crystal/monomer mixture having a spatially inhomogenous polymer network structure, and an electrode for applying a substantially uniform voltage to the nematic liquid crystal/monomer mixture. The lens is created within a cell by applying a substantially uniform electric field to the nematic liquid crystal/monomer mixture within the cell, while simultaneously irradiating the nematic liquid crystal/monomer mixture using a laser beam having a shaped intensity distribution, so as to induce formation of a spatially inhomogenous polymer network structure within the cell.

    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.

    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: 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
