Abstract
A method is presented to realize real time nonlinear operations on two dimensional images through the use of multiple liquid crystal light valves. The technique allows the use of either coherent or incoherent illumination and provides for real time control and alteration of the specific nonlinear operation being performed. Experimental results are given for level slice, logarithm, exponentiation, and A/D conversion.
