Image Processing Applications of the Liquid Crystal Light Valve.

Abstract

The liquid crystal light valve (LCLV) is employed toward three distinct real-time applications in coherent optical processing. First, it is demonstrated that a real-time system for resolution improvement of distant objects (whose spin Doppler-encodes reflected laser light) is feasible. Secondly, a method for obtaining range-slice images of laboratory models is shown. Further processing, which leads to simulated range-Doppler reference images (like those obtainable from microwave radar), is then demonstrated. The third application of the LCLV uses the device integration time to discriminate dramatically between moving and static speckle in an input image. Real-time image discrimination of slowly moving, laser-illuminated camouflage is therefore possible. (Author)
