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 or higher in color. A laser beam focusing arrangement aligns a mechanical axis of a focusing lens with an optical axis along which a laser beam is directed to reduce pointing errors.
