Abstract

A correlator performs better if the input and filter are made compatible with each other. To date, most quantitative work has been spent on improving filters. We give general rules for mutually optimizing input image conversions and filter SLM control. The rules take into account several realistic system considerations, including phase and amplitude coupling of input and filter modulators, inherent system noise, and a wide variety of quadratic ratio metrics.
