"Optical Laboratory Comparison Of Computer Generated Holograms For Correlation Matched Spatial Filters"

We consider various types of optical computer generated holograms (CGHs) using various encoding techniques. The application chosen is their use as optical matched spatial filters (MSFs) in an optical frequency plane correlator. This differs significantly from the use of CGHs for image reconstruction. Optical laboratory data is presented comparing the major types of CGHs on the same input data, using binary CGHs. The various issues associated with this use of CGHs are noted and quantified with optical laboratory data.
