Abstract
Invariant pattern recognition systems are based on spatial filters that are in most cases computer-generated holograms. Logarithmic harmonics were suggested to be used in implementations that perform projection invariant pattern recognition. A novel approach for optical generation of logarithmic harmonic matched filters of a universal nature, usable for arbitrary input patterns, is presented, followed by some initial experimental results.
