    摘要: A motionless adaptive focus stereoscopic scene capture apparatus employing tunable liquid crystal lenses is provided. The apparatus includes at least two image sensors preferably fabricated as a monolithic stereo image capture component and at least two corresponding tunable liquid crystal lenses preferably fabricated as a monolithic focus adjustment component. Using a variable focus tunable liquid crystal lens at each aperture stop provides constant magnification focus control. Controlled spatial variance of a spatially variant electric field applied to the liquid crystal of each tunable liquid crystal lens provides optical axis shift enabling registration between stereo images. A controller implements coupled auto-focusing methods employing multiple focus scores derived from at least two camera image sensors and providing multiple tunable liquid crystal lens drive signals for synchronous focus acquisition of a three dimensional scene. Wafer manufacture provides a compact stereoscopic image capture apparatus for endoscopic surgery, optical inspection and entertainment applications.

    摘要: By adjusting a state of circular polarization of a laser beam, a rate of rotation in micro objects rotated by angular momentum imparted from the light is controlled. The light has greatest effect on anisotropic transparent micro objects. A micro mixer using anisotropic micro probe objects can also be provided by using the light to control rotation of the probe objects in a suspension or solution.

    摘要: Liquid crystal optoelectronic devices are produced by fabricating a wafer-level component structure and affixing a plurality of discrete components to a surface structure prior to singulating the individual devices therefrom. After singulation, the individual devices include a portion of the wafer-level fabricated structure and at least of the discrete components. The wafer-level structure may include a liquid crystal and controlling electrodes, and the discrete components may include fixed lenses or image sensors. The discrete components may be located on either or both of two sides of the wafer-level structure. Multiple liquid crystal layers may be used to reduce nonuniformities in the interaction with light from different angles, and to control light of different polarizations. The liquid crystal devices may function as optoelectronic devices such as tunable lenses, shutters or diaphragms.
