The light guide system includes a transparent light-incident portion that includes a light-incident surface on which the image light beams are incident and which is a curved surface, and a plurality of reflection surfaces which convert the image light beams incident from the light-incident surface into parallel light beams and are curved surfaces, and a transparent light guide portion of which one end side in a first direction is connected to the light-incident portion. In the light guide portion, the image light beams incident from the light-incident portion are reflected between a first surface and a second surface, and are guided to a light-emitting portion.

  • Patent number: 10497141
    Abstract: A brightness image of a scene is converted into a corresponding frequency domain image and it is determined whether a threshold condition is satisfied for each of one or more regions of interest in the frequency domain image, the threshold condition being that the number of frequencies in the region of interest is at least as high as a threshold value. The results of the determination can be used to facilitate selection of an appropriate block matching algorithm for deriving disparity or other distance data and/or to control adjustment of an illumination source that generates structured light for the scene.

  • Patent number: 10474041
    Abstract: The present disclosure generally relates to lithography devices comprising an autofocus system. The autofocus system is configured to individually focus and adjust a plurality of digital micromirror devices. The autofocus system comprises a single light beam and a diffractive optical element configured to split the single light beam into two or more split beams. The two or more split beams are directed to a beam splitter. The two or more split beams are then reflected off the surface of a substrate to at least one position sensor. The position sensor is configured to measure the position of each of the two or more split beams. At least one digital micromirror device is then individually adjusted based on the measured position to adjust the focus of the at least one digital micromirror device with respect to surface height and tilt variations of the substrate.

  • Patent number: 10453162
    Abstract: A monochrome imager used in such systems as a scanner can detect watermarks that have been encoded in the color space or chrominance. Such watermarks are called chroma watermarks and are considered more reliable than the traditional classic watermarks, which are encoded based on luminance. The monochrome imager detects the chroma watermark, which has been illuminated with ambient white light from a blue light emitting diode (LED) coated with phosphor.
