Patent ID: 7997735

Claim:
A laser projection system comprising a system controller, a visible light source, and a light disrupting element, wherein the visible light source comprises at least one laser, and the laser projection system: generates at least a portion of a scanned laser image by operating the laser for optical emission of encoded image data and controls a scanning element to scan an optical signal of the visible light source across a plurality of image pixels, wherein the scanned optical signal comprises a low spatial frequency beam and a high spatial frequency beam, and the low spatial frequency beam generates a low spatial frequency image having spatial frequencies below a spatial frequency threshold, the high spatial frequency beam generates a high spatial frequency image having spatial frequencies that are above the spatial frequency threshold, and the scanned laser image is a sum of the high spatial frequency image and the low spatial frequency image; and alters the low spatial frequency beam by directing and focusing the low spatial frequency beam upon an out of focus light disrupting element, wherein the light disrupting element is out of focus with respect to an intermediate image that is formed by scanning and focusing the low spatial frequency beam, and the low spatial frequency beam and the high spatial frequency beam are generated by a single laser and a beam splitting element.
