Abstract
A lightweight, compact image projection module, especially for mounting in a housing having a light-transmissive window, is operative for sweeping a composite laser beam as a pattern of scan lines on a planar projection surface and for causing selected pixels arranged along each scan line to be illuminated to produce an image, especially in color. The raster pattern extends along mutually orthogonal directions that are generally parallel to mutually orthogonal dimensions of a support of the module. The image is level with the horizontal.
