ABSTRACT:
1. A system for coding optical images comprising, in combination, first and second geometric arrays of light-conducting elements, similar elements of each array being scrambled in a random fashion such that the respective ends of these conductors occupy different relative positions at both ends of the array, said arrays being coupled end to end, and means for varying the position of one of said arrays with respect to the other whereby an image passing through said arrays is subjected to different coding in each of said arrays.
