Novel applications of PMMA-modulator-polarizer configurations in analog optical processing are described. The PMMA system, consisting of two polarization modulators and two crossed polarizers, can perform addition as well as subtraction and multiplication. Experimental results obtained with a laboratory assembly made up of two photoelastic modulators and a pair of Glan-Thompson prisms confirm the theory. It is concluded that complex structures consisting of a multitude of programmable PMMA processors having high processing speeds can be realized by fiber and integrated optics technology.
