A systems approach to electro-optics, serving both as an advanced college textbook and as a professional reference to principles, techniques, and applications. Introduces fundamentals of geometric and physical optics, optical radiation, and laser electro-optical modulation. In addtion to coverage of basics, it surveys techniques used to analyze electro-optical devices and systems, and detect optical radiation. Numerous exercises, examples and problems illustrate the application of theory and techniques to a variety of areas including detector arrays and imaging tubes, electro-optical sensors, and optical signal processing.
