Paper Abstract

Several pure optical processing methods have been investigated in order to improve the quality of images from a military environment. Two methods proved unsuitable from the military viewpoint: the well know Vander Lugt matched filter and the classical spatial filtering by a 4f system with coherent illumination. On the other hand two other methods gave encouraging results : pseudocolour encoding of spatial frequencies and cryptography by means of a double aberrating medium. I.
