Paper Abstract

An optoelectronic neocognitron neural network has been built at JPL and demonstrated for various automatic target recognition applications. A new technique of constructing and storing a large holographic synapses array at the Fourier plane has enabled the shift-invariant target recognition and tracking. In this paper, a recent development of an innovative bipolar holographic synapses synthesis technique is reported. Experimental demonstration of increased discrimination capability using this bipolar synapses is also provided.
