Abstract

We implement optical logic operations, using a polarization-encoding architecture based on digital speckle pattern interferometry (DSPI). The method is based on the intensity dependence of DSPI on the rotation of the polarization direction in the paths of the interferometer between acquisition of frames. The 16 two-input logic operations can be achieved and stored in a host computer. This scheme also offers the possibility of creating dynamic logic gates.
