Patent ID: 8130433

Claim:
A laser projection system comprising a light source, scanning optics and spinning optics, wherein: the light source comprises at least one laser configured to emit an output beam; the scanning optics is positioned in an optical path of the output beam and configured to scan the output beam across a plurality of image pixels on a projection surface through the spinning optics; the spinning optics is configured to: create a virtual image of the scanning optics; translate the virtual image and change the angle of incidence of the output beam on the projection surface as the virtual image is translated; and the laser projection system is programmed to: generate at least a portion of a scanned laser image on the projection surface by operating the laser for optical emission of encoded image data and controlling the scanning optics to scan the output beam across the plurality of image pixels; execute the translation of the virtual image by moving the spinning optics as the output beam is scanned across the plurality of image pixels on the projection surface; and compensate for a relative image shift resulting from the translated virtual image.
