Paper Abstract

An architecture for a real-time signal correlation based on optical joint transform correlation is proposed. Two parallel on-plane acousto-optic (AO) cells and a liquid crystal light valve (LCLV) are employed to produce crosscorrelation of two electrical signals. Arranging two AO cells on the same plane, this architecture can be implemented in a compact form. The proposed architecture has a capability of performing parallel multiple crosscorrelations by adding AO cells on the input plane. The theoretical analysis and preliminary experimental results are presented.
