    摘要： A laser radar includes: a laser, an optical transmission system, a 1-dimensional array of photo-detectors, an optical reception system, and an electronic control system. The laser emits a wavelength of light, and the optical transmission system shapes the light into a beam, and scans the beam along a fan of transmission light paths toward a target. The photo-detectors are capable of time-of-arrival measurements and are sensitive to the wavelength of light. The optical reception system collects the laser light reflected from the target along a fan of reception light paths. The electronic control system synchronizes the scan of the beam with a respective time-of-arrival measurement from each of the photo-detectors, and analyzes the time-of-arrival measurements. The system is configured for all of the transmission light paths and all of the reception light paths to lie in one plane, with all of the reception light paths intersecting with at least one of the transmission light paths.

    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： 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 of scan lines to be illuminated to produce an image of high resolution in color. The direction of scanning of the scan lines is switched between alternate frames, and the resulting image is the superposition of successive frames integrated for viewing by the human eye.

    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.
