Abstract

The nonlinearity of the wire-grid liquid crystal light valve (WG-LCLV) is used to implement the nonlinear joint transform correlator for optical pattern recognition. Experimental results and computer simulations show the nonlinear characteristic of the WG-LCLV can produce well defined correlation peak and high peak to noise energy ratio.
