An Ultra-High Speed Incoherent-to-Coherent Converter for Optical Computing.
Abstract
Many optical computing problems are centered around the processing of incoherent images. These images may be conventional visible light such a's those taken with a CCD imager or camcorder. They may also take the form of infrared images in the case of missile seekers or x-ray images from medical or other sources. For optical processing, these images must be converted to either phase or amplitude modulated coherent light. This is typically accomplished by electronically feeding the originally captured image into a spatial light modulator (e.g., liquid crystal or deformable mirror array) and modulating a coherent reference beam with the 2 dimensional data pattern.
