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 arrangement for and a method of collecting and displaying information in real time along a line of sight from a human operator to remote targets located at variable distances therefrom and identifiable by machine-readable indicia. A two-dimensional image is automatically projected along the line of sight on the target alongside the indicia while maintaining the image size relatively constant over an extended range of working distances.

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 plurality of image projection modules is operative for causing selected pixels in overlapping raster patterns to be illuminated to produce a large size image of high resolution of VGA quality in monochrome or color. The selected pixels in an overlap region of the patterns are illuminated at a lesser intensity to provide uniform brightness over the image. Multiple single mode lasers, or a multimode laser with an aperture stop, are employed to increase laser output power. Speckle noise is reduced by controlling the optical transmission characteristic of a projection screen. Three-dimensional images are generated by moving the screen. Cross-coupling between drive and feedback mechanisms in image projection is reduced for better image quality.
