Informational Capacity of Coherent Optical Processing Systems
Abstract
Let us consider an image optical filtering system which is one of the coherent optical processing systems. Pig. 1 shows that the monochromatic point-source light is collimated by the lens LK, forming the plane wave-front in the input of the system on the plane P1. An image to be filtered is put on this plane. The Fourrier-transform lens L1 is placed at a distance “f” from the plane P1. In the so-called frequency plane P2. the spatial image spectrum is distributed with an accuracy to some constant. This spectrum can be modified by a filter placed at the same plane. The lens L2 produces the second Pourrier-transform of the filtered spectrum and generates a processed image at the output plane P3.
