  • Patent number: 8519983
    Abstract: Briefly, in accordance with one or more embodiments, an input device may be utilized in conjunction with a scanned beam display or the like, or may be based on the scanning platform as used in a scanned beam display such as a MEMS based scanner. An input event such as illumination of a photodetector or reflection of a scanned beam off of a retroreflector may be correlated with a timing event of the scanning platform such as a refresh signal, or a horizontal and vertical sync signals. The correlation of the timing event may be representative of an X-Y location, and in some embodiments of a Z location, that may be utilized to provide input data back to a host device.

  • Patent number: 8355013
    Abstract: An integrated photonics module may include a selective fold mirror configured to pass at least a portion of emitted light toward the MEMS scanner and reflect scanned light through to a field of view. The selective fold mirror may use beam polarization to select beam passing and reflection. The integrated photonics module may include a beam rotator such as a quarter-wave plate to convert the polarization of the emitted light to a different polarization adapted for passage through the fold mirror. The integrated photonics module may include one or more light detectors.

  • Patent number: 7954953
    Abstract: A scanning beam overlay projection system displays an image on a projection surface by scanning a light beam in a raster pattern. Reflective spots on the projection surface reflect light back to the projection system when illuminated by the light beam. A photodetector in the projection system detects the reflected light, and timing circuits determine where in the raster pattern the reflective spots are located. The image can be scaled and warped to correlate tagged points within the image with the locations of the reflective spots on the projection surface.
