ABSTRACT:
A lightweight, compact image projection module, especially for mounting in a housing having a light-transmissive window, is operative for causing selected pixels in a raster pattern to be illuminated to produce an image of high resolution of VGA quality in color. A compact acousto-optical modulator is used to modulate a green laser beam used to produce the image.
