  • Publication number: 20210011282
    Abstract: The present invention provides an optical scanning device capable of optical scanning without reducing the spatial resolution even when the scanning range is expanded. The optical scanning device 100 comprises: a light source 101 emitting a light; a scanning mirror 106 that includes a reflecting plane reflecting a light entering from the light source and that is allowed to oscillate independently around each of a first axis extending in the reflecting plane and a second axis orthogonal to the first axis and extending in the reflecting plane; and a controller 103 controlling the scanning mirror in terms of a first frequency and a first amplitude of oscillation around the first axis as well as a second frequency and a second amplitude of oscillation around the second axis for scanning with the light reflected by the reflecting plane of the scanning mirror. The controller 103 controls the second frequency based on the maximum scanning angle in the sub-scanning direction.

  • Publication number: 20200096611
    Abstract: An optical scanning apparatus includes a light source, a substrate, a reflection member, a drive unit, and a controller. A scanning mirror and an attitude detector are integrated with substrate. An attitude detector outputs a first signal according to an attitude angle of substrate. A reflection member reflects a light beam reflected by scanning mirror. A drive unit can adjust an inclination of reflection member with respect to a main surface of substrate. A controller controls drive unit based on first signal. For this reason, an outgoing angle of light beam from optical scanning apparatus with respect to a horizontal surface can stably be maintained regardless of the inclination of optical scanning apparatus with respect to horizontal surface.

  • Patent number: 7624638
    Abstract: First and second detection frames are supported by a substrate to be rotatable about first and second torsion axes. A first link beam is connected to the first detection frame on an axis located at a position moved from a position of the first torsion axis in a first direction crossing the first torsion axis and directed to one end side of the first detection frame. A second link beam is connected to the second detection frame on an axis located at a position shifted from a position of the second torsion axis in a second direction opposite to the first direction. An inertia mass body is displaceable in a thickness direction of the substrate by being linked with the first and second detection frames by the first and second link beams, respectively. This constitution makes it possible to obtain a highly precise acceleration sensor hardly influenced by disturbances.

  • Patent number: 6955086
    Abstract: An acceleration sensor includes first and second fixed electrodes on a substrate, and a movable electrode located above the first and second fixed electrodes, with respect to the substrate, and facing them. The movable electrode is elastically supported on the substrate by a first elastic supporting body and is movable. A mass, which is elastically supported on the substrate by a second elastic supporting body, moves in response to an acceleration in a direction perpendicular to the substrate. A linking portion links the movable electrode and the mass at a position spaced from an axis of movement of the movable electrode by a distance. Acceleration is measured based on changes in a first capacitance between the first fixed electrode and the movable electrode and a second capacitance between the second fixed electrode and the movable electrode. Thus, a highly impact resistant and highly reliable acceleration sensor is obtained.
