Abstract
A fractional correlator that is based on the anamorphic fractional Fou rier transform is defined. This new, to our knowledge, correlator has been extended to work with multiple filters. The novelty introduced by the suggested system is the possibility of the simultaneous detection of several objects in different parts of the input scene (when anamor phic optics are dealt with), thereby permitting an independent degree of space invariance in two perpendicular directions. Computer experime nts as well as experimental optical implementation are presented. (C) 1996 Optical Society of America
