Paper Abstract

Spatial light modulators used as inputs to optical correlators often modulate both the amplitude and phase of the coherent illumination. This means that matched filters commonly used are not truly matched to the scenes displayed on these modulators. Filters are normally calculated from an assumed amplitude-only input. A few analytically manageable examples are given which demonstrate the errors that can occur and suggestions are made for using the phase modulating characteristics to an advantage.
