Pixel-by-pixel array division by optical computing.
An optical system, which divides two arrays in real time, has been conceived and demonstrated for the first time to our knowledge. The pixel-by-pixel division, performed with analog signals, treats two incoherently illuminated arrays in parallel. The configuration used is a feedback arrangement with the data introduced in the loop through two optical image converters (liquid-crystal light valves in our experiments). Analysis of the circuit and experimental results are presented.
