ABSTRACT:
A scene projector displays an image as M by N array of pixels. The scene projector includes a plurality of optical guided wave modulators. The modulators each have an optical input, and optical output and an electrical input. The optical output of each of the modulators forms a corresponding one of the pixels. The optical input of each of the modulators is adapted to be uniformly illuminated. The scene projector further applies a selected voltage to the electrical input of each of the modulators. This voltage is selected commensurately with a predetermined intensity of output optical energy at the corresponding pixel.
