Abstract
We will describe a technique of optical information processing by a spectrally broad-band light source (e.g., white light). This technique enables the signal processing to be carried out in complex amplitude rather than in intensity. The basic advantage of the white light processing technique is the elimination of the coherent artifact noise that frequently plagues the coherent optical processing system. We will show that this white light processor is capable of performing complex signal filterings that a coherent optical processor can offer. We will demonstrate that signal detection by complex spatial filtering and image addition and subtraction can be carried out by this white light processing technique. Although this processing technique is effective in one dimension, however, it can be applied in 2-D problems in optical information processing.
