Matched Filtering with Achromatic Optical Correlators.

Abstract

An achromatic Fourier transform system for use in an optical correlator has been designed and used with incoherent light to obtain autocorrelations of pictures of aerial views of urban areas. The necessary optics included achromatic lenses and some highly achromatic holographic elements in a unique arrangement to produce wavelength independent Fourier transforms. (Author)
