Abstract
In this paper we theoretically analyze and demonstrate that a photorefractive correlator, originally proposed by D. M. Pepper and later implemented by J. O. White and A. Yariv as well as many others, can be used to realize adaptively a wide variety of optimal correlation filters such as the matched filter, the inverse correlation filter, the maximum discrimination correlation filter and several trade-off correlation filters.
