  • Patent number: 10067345
    Abstract: The present invention addresses the problem of providing a head-up display device with which the display quality of a display object can be improved. A mirror holder 30 supporting a concave mirror is equipped with a protruding piece that protrudes from the approximate center of the holder width, which is defined along a rotational axis, and this protruding piece is moved by a position adjustment means. Stress acting on the mirror holder from the protruding piece is uniform in the left and right directions from the center of the mirror holder. Consequently, twisting at the location of the mirror holder is significantly reduced, so the driver is able to view a display object for which distortion has been suppressed, and the display quality of the display object is improved.

  • Patent number: 10042145
    Abstract: High resolution printing systems that utilize high power laser diode bars and digital mirror devices (DMD) require side-by-side stacking of illumination modules to stitching of the image from each module to form a longer total image width. An inline illumination optical system having a refractive prism and Total Internal Reflection (TIR) prism pair with an air gap along with a light guide transporting light beams at a compound angle to the prism pair eliminates the need for any axial rotation of the laser and light guide, and enables side-by-side module stacking. The illumination optical system includes an illumination module having a light source, the light guide, a DMD array and a Refractive TIR (RTIR) prism. The system also includes a DMD housing containing the DMD array and having a width within which the illumination module is confined to allow side-by-side stacking.

  • Patent number: 10018834
    Abstract: A method and apparatus for performing foci array scanning using at least one adjustable or tilting medium is disclosed. The medium can be controllably tilted in order to translate a beam of electromagnetic radiation perpendicularly to its propagation, and upon exiting the medium, will propagate in the original, incoming direction. This allows the apparatus that emits the radiation, such as a laser, to remain stationary and still scan a 2D array. Additionally, the reflected fluorescence light undergoes the opposite shift to “reverse” the scanning shift and bring the beamlets back in line with a lenselet array. So the collection fibers can remain static and collect light from different spots on the sample from during the scan.

The display engine comprises a pair of single axis MEMS (Micro Electro Mechanical System) scanners that are configured to reflect the image light through horizontal and vertical scan axes of the display system's field of view (FOV) using raster scanning. The MEMS scanners are arranged with their axes of rotation at substantially right angles to each other and operate with respective quarter wave retarder plates and a polarizing beam splitter (PBS) to couple the image light into an in-coupling DOE in the waveguide display without the need for additional optical elements such as lenses or relay systems.
