This work offers detailed discussions on all aspects of acousto-optic deflectors, modulators and tunable filters, emphasizing hands-on procedures for design, fabrication and testing. It contains previously unpublished treatments of acousto-optic device design and impedance matching, permitting the actual design of real devices and device-matching circuits.Principles of acousto-optics; design of acousto-optic deflectors; design of acoustic-optic modulators; acousto-optic tunable filters; transducer design; acousto-optic device manufacturing; testing of acousto-optic devices.
