    摘要： 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.

    摘要： A method and apparatus are provided for controlling the operation of a Laser Projection Display (LPD). Generally, the LPD is comprised of a laser, an optical system and a controller. The laser is adapted to emit a beam of laser light. The optical system is adapted to scan the beam of laser light on a display surface in a two-dimensional raster pattern. The controller is adapted to control the rate at which the laser beam is scanned to produce regions of varying resolution on the display surface. The controller is also adapted to present laser light onto the display surface within only selected portions of the two-dimensional raster scan pattern so that spaced apart image regions may be created.

    摘要： A lightweight, compact image projection module has a laser assembly for emitting a plurality of laser beams of different wavelengths, an optical assembly for focusing and nearly collinearly arranging the laser beams to form a composite beam, a scanner for sweeping the composite beam in a pattern of scan lines, each scan line having a number of pixels, and a controller for causing selected pixels to be illuminated, and rendered visible, by the composite beam to produce the image. An aperture stop located between the laser assembly and the scanner, limits a cross-sectional dimension of at least one of the laser beams to below a prescribed level to preserve color fidelity over the image.
