A composable mask for optical processing of light energy of known wavelengths is provided having a large number of discrete, uniformly spaced light valves or cells, each cell fabricated of a thin coating of an electrochromic material whose light transmissivitiy may be individually controlled by the random address of each cell through the application of appropriate electrical potentials through translucent electrodes. The degree of resolution obtainable through the use of a mask is determined by the number and size of the light valves. Author
