  • Arrangement for and method of increasing pixel symmetry, especially for image projection arrangements
    Publication number: 20060262179
    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 in color. The pixels are rendered symmetrical in cross-section by aligning a narrow dimension of a beam spot of a laser beam along scan lines of the raster pattern.

  • Color image projection system and method
    Publication number: 20060126023
    Abstract: An image projection system projects an image on a projection screen having a phosphor for converting incident violet light into green light which, together with red and blue light, creates the image in full color. The screen includes an apertured mask having apertures filled with the phosphor, or a phosphor plate in contact with the mask and having lenslets extending through and past the apertures.

  • Method and apparatus for controllably reducing power delivered by a laser projection display
    Patent number: 7030353
    Abstract: 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.

  • Monitoring light beam position in electro-optical readers and image projectors
    Publication number: 20060065735
    Abstract: 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.

  • Method and apparatus for controllably compensating for distortions in a laser projection display
    Publication number: 20050279922
    Abstract: A method and apparatus are provided to controllably compensate for distortions in an image produced by an LPD, where the distortion arises from the shape and/or angle of the viewing surface relative to the LPD. For example, the LPD can determine the angle of the viewing surface relative to the LPD and then adjust the horizontal and vertical scan mechanisms to return the image to its original configuration, such as rectangular.
