3Acousto-Optics, Optical Computing, and Signal Processing

We first address the acousto-optic (AO) effect called Bragg diffraction, utilized in devices called Bragg cells. The basic operating principles of Bragg cells, the components, the applications, and the performance of some systems developed using Bragg cells will be discussed. The implementations of the AO effect are widespread. Much research continues due to the potential for great speeds and small size of optical processing devices. AO Bragg cell signal processing is an analog technology showing great promise, in an age where digital electronics is most emphasized.

3.1 Principle of Operation

Acousto-optics deals with the interaction of sound and light. In Bragg cells, the AO interaction ...
