Abstract
A method and apparatus for operating an electro-optical array. Images indicative of shapes are obtained in some way, and these images are processed. The processed image is then used to drive an electro-optical array, such as a liquid crystal display, such that some parts of the display are opaque and other parts are transparent. A light source is directed through the liquid crystal array and thereby generates a light signal having the same shape as those parts of the liquid crystal array which are transparent.
