  • Patent number: 10495955
    Abstract: Methods and apparatuses for controlling a projector are provided. In some embodiments, a method includes: controlling the light source to emit point structured light to a reflector; and adjusting a tilt angle of the reflector to change the tilt angle of the reflector, and to enable the point structured light reflected from the reflector to an optical conversion device to deflect towards a preset scanning direction. The optical conversion device is used for converting the point structured light incident onto the optical conversion device into line structured light. The line structured light is used for forming a pattern that is projected onto a surface of a target object and extends along a direction intersecting with the preset scanning direction. Improved efficiency in three-dimensional scanning of a target object can be achieved.

  • Publication number: 20120250160
    Abstract: Roughly described, an optical device has first and second waveguide segments which are constructed such that irradiation changes both average refractive index and also birefringence in the respective segment. The change in birefringence as a function of the change in average refractive index, is different for the two segments. Predetermined lengths of each of the two segments are irradiated. In an MZI, the technique can be used to adjust simultaneously for one or more of differential path length phase delays, coupler-induced phase errors, and frequency errors.

    Abstract: The present invention provides a synthetic silica glass for an optical member in which not only a fast axis direction in an optical axis direction is controlled, and a birefringence in an off-axis direction is reduced, but a magnitude of a birefringence in the optical axis direction is controlled to an arbitrary value, such that an average value of a value BR cos 2?xy defined from a birefringence BR and a fast axis direction ?xy as measured from a parallel direction to the principal optical axis direction is defined as an average birefringence AveBR cos 2?xy, and when a maximum value of a birefringence measured from a vertical direction to the principal optical axis direction of the optical member is defined as a maximum birefringence BRmax in an off-axis direction, the following expression (1-1) and expression (2-1) are established: ?1.0?AveBR cos 2?xy<0.0??(1-1) 0.0?BRmax?1.0??(2-1).

  • Patent number: 8174769
    Abstract: Embodiments of the present invention are directed to beamsplitters that include optical elements to correct for beam offset. In one embodiment, a beamsplitter includes a first plate having two approximately parallel and opposing planar surfaces and a partially reflective layer coating one of the planar surfaces, and a compensator plate having two approximately parallel and opposing planar surfaces. The compensator plate is positioned so that an incident beam of light passing through the compensator plate acquires a first beam offset. Subsequently, the incident beam of light with the first beam offset passing through the first plate is split into a reflected beam and a transmitted beam by the partially reflective layer where the transmitted beam has a second beam offset that substantially cancels the first beam offset such that the transmitted beam is approximately parallel to and aligned with the incident beam.

  • Patent number: 8149494
    Abstract: A monolithic Mach-Zehnder Interferometer (MZI) is provided for photon beam-splitting and beam-combining with accurate super-positioning of the outgoing beams, which creates the interference. The MZI includes a complimentary pair of right-isosceles triangular prisms, and several reflector units. The triangular prisms are configurable to physically join together along associated hypotenuse surfaces that form a beam-splitter interface, thereby producing a rectangular prism having a square cross-section with four outer side surfaces. Each reflector unit forms a right-isosceles mirror that rigidly faces a corresponding surface of the four outer side surfaces of the rectangular prism. The MZI further includes a spacer disposed between the corresponding surface and the each reflector unit.

  • Patent number: RE43089
    Abstract: In one form, an imaging system comprises an imager that forms an image of an object in a field of view, a rotationally symmetric lens assembly disposed between the imager and the object, and an equalizer. The rotationally symmetric lens assembly provides increased collection efficiency for a given depth of field, whereby the rotationally symmetric lens assembly causes aberration, compared to a well-focused lens. The rotationally symmetric lens assembly comprises a front negative lens, a rear positive lens, and an aperture positioned between the front and rear lenses. The equalizer, which is connected to the imager, receives image data and at least partially compensates for the aberration caused by the rotationally symmetric lens assembly.
