Paper Abstract

Computer simulations of the scaling and rotation sensitivity of a phase-only filter were performed, showing that it is much more sensitive to such input variations than is a classical matched filter. Values of the peak correlation spot power versus both rotation angle and scale factor are presented for both filter types. Several theorems are derived for calculating the optical efficiency of any filter in both input space and frequency space.
