Paper Abstract

We show that certain additions to the mathematical model of a correlator can improve the signal to noise ratio of the optical correlator itself. All computational optimizations include a digital simulation process as a critical tool. The more accurate the model of the optical correlator, the better the optimization. improvements to our correlator model, based on correlator measurements, are made to the simulator in our filter optimization process. Comparisons of the signal to noise ratio are made both digitally and optically. Laboratory results are given.
