Abstract

Optimum performance in an acousto-optic processor often requires signal preconditioning. Necessity for fast programmable adaptable wideband notch filters has led to the use of the surface acoustic wave (SAW) transform domain filter which operates by filtering in the frequency domain. We consider analysis of an acousto-optic (AO) system with a SAW filter as a component. DFT-based simulation methods for the AO spectrum analyzer, AO correlator, and SAW filter are examined. Simulation results are compared to system responses for an AO spectrum analyzer. SAW filter effects in an AO correlator are explored, and simulation results presented. The generalized simulation techniques are shown to be applicable to other AO information/signal processors, and may be utilized to examine new architectures.
