  • Publication number: 20210318473
    Abstract: A method for manufacturing a concave diffraction grating is provided. The method includes the steps of: positioning a flat mold and a concave substrate such that a pressing surface, having a groove pattern of a diffraction grating, of the flat mold faces a concave surface, coated with a resin, of the concave substrate; pressing the pressing surface against the resin coated over the concave surface by pressurizing the flat mold using a fluid; and curing the resin having the groove pattern transferred thereto by being pressed by the pressing surface. This makes it possible to improve load non-uniformity and manufacture a concave diffraction grating with high surface accuracy.

  • Publication number: 20180176524
    Abstract: The laser projection display device includes a scanning mirror reflecting and two-dimensionally scanning a laser beam emitted from a laser light source and sensors detecting rotation angles of the scanning mirror, and controls driving of the scanning mirror on the basis of sensor signals output from the sensors. At this time, a temperature compensation unit compensates for temperature dependency of a transfer characteristic of a signal transmission line for transmitting the sensor signals according to a temperature measured by a thermometer arranged in the vicinity of the scanning mirror. In order to correct amplitudes and phases of the rotation angles of the scanning mirror obtained from the sensor signal, the temperature compensation unit includes a look-up table storing correction amounts for each temperature.
