Abstract

An experimentally based technique is presented which improves the signal to noise ratio in the detector plane of an optical correlator. The technique utilizes off-line processing by a digital computer at the current stage, but optical and hybrid architectures can be envisioned which would allow the processing to be done in real time (speed of detector).
