摘要： A lightweight, compact image projection module has a laser package having a common exit port, and a plurality of lasers mounted in the package and operative for emitting a plurality of laser beams of different wavelengths through the common exit port. An optical assembly focuses the laser beams exiting the common exit port, and includes a common focusing lens through which the laser beams pass along respective paths that are in angular misalignment. An optical corrector element in at least one of the paths corrects the misalignment to produce aligned beams. A scanner sweeps the aligned beams in a pattern of scan lines, each scan line having a number of pixels. A controller causes selected pixels to be illuminated, and rendered visible, by the aligned beams to produce 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： An image projection system projects an image on a projection 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.
