  • 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.

  • Publication number: 20160086628
    Abstract: Diffracted light generated by a recording medium in reproduction is largely blocked by a spatial filter because of a position shift of the recording medium. Thus, the light amount of the diffracted light converged onto an optical detector is reduced and a satisfactory level of a reproducing signal cannot be obtained. In addition, in recording, it is necessary to fix the position of the spatial filter in rays for removing unnecessary frequency components or the like in a light beam emitted from a light source. In actuators having at least two spatial filters, one spatial filter is mounted on an actuator driven along two or more axes and moves independently of another spatial filter, and the other spatial filter is fixed to a common one-axis actuator. Switching of the positions of the spatial filters is performed by the common one-axis actuator.
