J. Garcia et al., SPACE-VARIANT SIMULTANEOUS DETECTION OF SEVERAL OBJECTS BY THE USE OFMULTIPLE ANAMORPHIC FRACTIONAL-FOURIER-TRANSFORM FILTERS, Applied optics, 35(20), 1996, pp. 3945-3952
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)
