Abstract

In this paper we present a multiple reference optoelectronic joint transfer correlator (JTC) in which the reference images are phase encoded using a pseudorandom phase sequence. The phase encoding is used to remove extraneous peaks from the correlation plane as well as improve the spatially efficiency of the JTC system. The reference images are phase encoded apriori making the system fast for real-time feedback. The optoelectronic joint transform correlator (JTC) is presented and analyzed as an effective optoelectronic correlator. The architecture of the proposed system is presented.
