Paper Abstract

Tracking algorithms that follow a correlation peak benefit from a close relationship between center of target and center of correlation peak. Filters constructed on spatial light modulators with coupled phase and amplitude may be optimized according to various criteria. Matched- phase filters are guaranteed to center the correlation peak, but matched phase does not result from optimizing a wide variety of metrics on a coupled modulator. Laboratory results reported here bear out previous conjecture that the largest peak shift is less than half a pixel per axis.
