MODIFIED ACOUSTO-OPTICAL SPECTRUM ANALYZER FOR COMPLEX SPECTRUM EVALUATION

摘要

An approach to implementing an acousto-optical spectrum analyzer for complex spectrum evaluation is considered. The scheme contains the light sources, which emit the information and reference optical beams, and arrays of fibers for accepting optical signals. We discuss the optical coherent heterodyning, which enables to evolve amplitudes and phases of the components of a frequency spectrum, and describe the performance of practical layouts.
