Image Subtraction by Polarization-Shifted Periodic Carrier.

Abstract

A coherent image subtractor is described that makes use of a periodic carrier that is effectively shifted by one-half period by simple sheet polarizing material. As the system has two input stations, the two transparencies to be subtracted are simultaneously visible to facilitate alignment. (Author)
