Paper Abstract

In this paper we propose the use of discrete pseudorandom phase mask for a spatially efficient phase encoded JTC. In the proposed JTC system the reference image is phase encoded using a pseudorandom phase mask to eliminate extraneous peaks cluttering or overshadowing the correlation output. The phase encoding scheme also eliminates the need for a spatial separation in the joint input image resulting in the full use of the SLM. An optoelectronic architecture of the proposed system is presented. To relax the need for a phase-only SLM with a high phase resolution we proposed the use of discrete pentary pseudorandom phase mask.
