Abstract

Although photorefractive (PR) filter has the advantage of large storage capacity, the thickness of the filter also impairs the target shift limitation. In this paper, we have investigated the thickness requirement, as imposed by the focal depth of the transform lens, and the shift-invariant, as imposed by the Bragg diffraction. The commonly used photorefractive-based correlators are studied, which are VanderLugt (VLC), joint transform (JTC), and reflective types (RD) correlators. We have shown that PR-RC performance better, in terms of shift-invariant tolerance.
