Begins with a comprehensive background of basic modern optical signal processing and its applications including theory and phenomenon of optical transformation, the fundamental concept of optical signal processing and architectures, selected techniques in coherent optics, white-light processing and its methodologies. Progresses to chapters on the advances of spatial-light modulators and detectors which contain key devices that make real-time processing and computing with optics possible, applications of photorefractive crystal to optical signal processing, digital-optical computing, optical neural networks--architectures, designs and models. Packed with references and problems.
