摘要： The invention concerns a projector includes a light generator that emits a first light and a second light of mutually differing color components, a light position detector disposed to receive light incident in a direction outside of the projection surface and that detects a position of the incident light, a light scanner that projects the image onto the projection surface by scanning the first light and the second light with a first scanning angle, and that directs the first light and the second light to the light position detector by scanning the first light and the second light with a second scanning angle that is larger than the first scanning angle, and an adjustor that adjusts an emission timing of the first light and an emission timing of the second light so as to suppress relative misalignment between the first light and the second light on the projection surface.

摘要： A laser projector for displaying an image on a screen includes an optical system in which a scan mirror directs laser light to a beam splitter. A portion of the split light is transmitted while another is directed to an optical detector (117). A detection surface (310) of the optical detector (117) is divided into regions C, E, F, G, and H. The optical detector (117) outputs detection signals corresponding to the amounts of light incident on the respective regions. A position detection controller (130a) calculates an image projection position based on timing at which a laser beam is incident on region C. A laser control circuit (120) adjusts the intensity of the laser beam emitted by a laser based on laser beam intensities detected in regions E to H arranged around region C.

摘要： A mirror actuator (10) includes a piezoelectric element (21) having a thickness in a direction perpendicular to a surface of the mirror (4), and a circular surface bonded to a circular rear surface of the mirror (4) such that the center of the circular surface of the piezoelectric element (21) and that of the circular rear surface of the mirror (4) match. The piezoelectric element (21) receives a potential to cause the circular surface bonded to the mirror (4) to expand/contract radially around 360 degrees by a uniform ratio to allow the mirror (4) to have a surface modified in geometry. The piezoelectric element (21) is adjusted in thickness so that as the piezoelectric element (21) expands/contracts, the piezoelectric element (21) allows the mirror (4) to have a surface with a ratio of a radius of curvature in a radial direction of the mirror (4) to that of curvature in a tangential direction of the mirror (4) of (cos (2θ) + 1)/2, where θ represents an angle of incidence on the surface of the mirror (4).

摘要： An optical pickup device has a variable-shape mirror (6) that reflects a light beam emitted from a light source and that, by use of piezoelectric elements (13) sandwiched between a support substrate (11) and a mirror portion (12) arranged to face the support substrate, corrects for wavefront aberrations in the light beam by deforming a mirror surface of the mirror portion, and converging means for directing, while condensing, the light beam reflected from the variableshape mirror to a recording surface of an optical recording medium. Let a direction perpendicular to the travel direction of the light beam emitted from the light source be the X direction on the mirror surface and let the direction perpendicular to the X direction be the Y direction on the mirror surface, the mirror surface is inclined about the X direction such that the mirror surface forms a predetermined angle relative to the travel direction of the light beam emitted from the light source. The piezoelectric elements are arranged symmetrically about the center axis of the mirror surface, with two of them arranged in the X direction and another two in the Y direction. The piezoelectric elements are arranged on the support substrate such that, when all of them are driven with equal voltages, the curvature of the mirror surface in the X direction relative to the curvature of the mirror surface in the Y direction fulfills a predetermined curvature ratio.
