Abstract

A new optical Fourier domain filtering scheme that combines the conventional optical space-invariant linear filtering with a self-pumped nonlinear optical phase-conjugation technique is proposed. The new method is used for a real-time detection and channel evaluation of the multi-path information needed in radar, sonar, and communication signal processing applications. Preliminary experimental demonstrations are included.
