Experimental realization of a multiproduct photorefractive correlation system for temporal signals.

The design and operation of a multidimensional photorefractive correlator is described. With a photorefractive medium as the integrator, this system effects the correlation of up to four time-evolving signals. The holographic correlation volume is viewed by projection onto a two-dimensional detector. The correlator is designed for use with binary-phase signals, especially pseudorandom noise sequences.
