    摘要： 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.

    摘要： An image projection module (20) within a housing (10) is operative for causing selected pixels in a raster pattern to be illuminated to produce an image on a display screen (12, 40) of VGA quality. The screen (12, 40) is modified and/or the bandwidth of a laser (25) is increased, to reduce speckle noise in the image.

    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： Red, blue and green lasers respectively emit a plurality of red, blue and green laser beams having respective output powers. The beams are optically focused and collinearly arranged to form a composite beam which is swept by a pair of scan mirrors in a pattern of scan lines on a projection surface, each scan line having a number of pixels. A controller causes selected pixels to be illuminated, and rendered visible, by the composite beam to produce an image. A safety circuit detects a malfunction of at least one of the lasers and the scan mirrors, and deenergizes the at least one of the lasers and the scan mirrors upon detection of the malfunction.

    摘要： An image projection system projects an image on aprojection screen having phosphor particles for converting incident violet light into green light which, together with red and blue light, creates the image in full color. The phosphor particles are bound in a binding material whose index of refraction matches the index of refraction of the phosphor particles to reduce back scattering of light.
