    摘要： 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 linear scan lines on a planar projection surface and for causing selected pixels arranged along each linear scan line to be illuminated to produce an image of high quality and in color.

    摘要： A method and apparatus are provided to controllably reduce power of a laser projection display (LPD) in response to detecting a variation in a viewing surface. During the operation of the LPD, a controller 142 monitors laser light being reflected from the viewing surface. Since the controller 142 “knows” the amount of power that the LPD is being instructed to deliver, it may compare the known power to the reflected laser light to determine if a foreign object may be in the path of the laser light, and therefore, affecting the magnitude of the laser light. The controller 142 responds to detecting such an event by reducing power to the lasers.

    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.
