摘要： Optical beams emitted by optical sources are incident on a mirror surface of a scan mirror in a substantially vertical direction and reflected in a substantially vertical direction by the scan mirror. The mirror surface of the scan mirror is driven to repeatedly rotate two-dimensionally by a predetermined scan angle by a scan mirror drive circuit. A polarized beam splitter causes the optical beam emitted by the optical source to be incident on the scan mirror through a quarter wave plate, and outputs the optical beam that has been reflected by the scan mirror and passed through the quarter wave plate toward the screen. A scan angle expander is arranged on the output side of the polarized beam splitter, whereby the scan angle of the optical beam is increased by N times.

摘要： Disclosed is an optical pickup and an optical disc device using the same, each including a laser diode, a photo-detector having a region divided into at least six photo-detection areas, and a diffraction grating disposed between the laser diode and the photo-detector and having a region divided into four areas by cross-shaped division lines. The diffraction grating divides a light beam reflected from an optical disc into four diffracted light beams. A focus error signal in accordance with a knife edge method and two kinds of tracking error signals in accordance with a push-pull method and a differential phase detection method are detected by irradiating the light beams diffracted at the areas of the diffraction grating on the detection areas of the photo-detector and/or at boundary lines therebetween, and arithmetically operating light intensity signals obtained from the detection areas of the photo-detector. As a result, there can be realized an optical pickup and an optical disc device, each of which can be matched with various optical discs different in structure by detecting a tracking error signal in accordance with the push-pull method and a tracking error signal suitable for a read only disc using only one photo-detector. Further, in the present invention, a holographic element can be used as the diffraction grating.

摘要： In an optical head, light from a semiconductor laser is directed through a condensing optical system with a condensing lens onto an optical information recording medium through a transparent substrate in the form of a light spot. A unit for producing a light spot position control signal and a unit able to move the light spot, which supports the objective lens for movement, position the light spot on an information track. Light reflected from the optical information recording medium is directed through a polarized light branching element to a photo detector. Also mounted for movement with the objective lens are a polarization conversion element, arranged between the optical information recording medium and the polarized light branching element in order to change the polarization state of light incident to the optical information recording medium and reflected therefrom and a polarization diffraction grating, the diffraction efficiency of which changes depending on the change in the polarization state of the incident light and the reflected light caused by the polarization conversion element. The light spot control signal is detected from both reflected light diffracted through the polarization diffraction grating and non-diffracted reflected light contained in the light which passes through the polarized light branching element.

摘要： The present invention provides a scan-type image display device. In the scan-type image display device, laser light sources respectively generate light beams of green, red and blue, which in turn are combined by dichroic mirrors to generate a first beam and a second beam. A deflecting mirror device two-dimensionally scans the first and second beams under the rotation of a deflecting mirror thereof. The outgoing directions of the first and second beams have an angular difference relative to the vertical direction of a screen, and an interval between the first and second laser beams is set to be larger than an aperture diameter defined by laser safety standards.
