    Abstract: A laser beam is swept by a scan mirror as a pattern of scan lines on a projection surface. Selected pixels arranged along each scan line are illuminated to produce an image. The laser beam is optically modified to form each scan line with a desired high resolution having no less than a desired large number of the pixels over an extended viewing range, by focusing the laser beam to form a beam waist having a scan dimension proportional to the resolution at a focal location positioned between the scan mirror and the projection surface.

    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.
