摘要： An arrangement for determining light beam position in an electro-optical reader, image projector and like devices includes a drive for moving a scanning light beam at a scan frequency across a target as a scan line, and an electro-optical feedback assembly operatively connected to the drive, for optically detecting scan line position during beam movement, and for generating a feedback signal at the scan frequency, the feedback signal being indicative of the scan line position. A feedback coil in the drive is eliminated to avoid electromagnetic coupling between multiple coils in the drive.

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.

摘要： A method and apparatus are provided to capture images using a laser projection display (LPD). In a full color LPD camera, three lasers (red, blue, and green) are deployed to scan an image and receive reflected laser light therefrom. The reflected laser light may be analyzed and assembled into a picture. The LPD may also be used to display the picture, to operate as a viewfinder, to print the picture, to operate as a range finder, and the like.
