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： 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.

The heating element can also have a measurable temperature coefficient; a controller for controlling the temperature of the heating element as a function of the temperature coefficient; wherein the temperature of the heating element can be controlled without using an additional temperature probe. And the heating element can also be used to control the curing of the material using the heat dissipation of the heater through the material, thereby providing a mechanical armature for the material and the waveguide; wherein the mechanical armature solidifies the attenuator.

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.
