Overview: The subject "optical signal processing" can and should include all aspects of optics and signal processing. However, that is too large a scope for a textbook that, like this one, is intended as an introduc- tion to the subject at a level suitable for first year graduate students of electrical engineering, physics, and optical engineering. There- fore, the subject matter has been restricted. The book begins with basic background material on optics, signal processing, matrix alge- bra, ultrasound and SAWs, and CCDs. One might argue about this choice of topics. For example, there alread
