    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.
