    摘要： A scanning beam display system includes an optical module, an image control module, and a display screen on which optical beams are scanned. The optical module includes a vertical adjuster placed in the optical paths of the beams to control and adjust positions of the optical beams along a generally vertical direction on the display screen, and a control unit configured to receive control instructions for the vertical adjuster and to control the vertical adjuster to be at one of a predetermined number of orientations to place the scanning optical beams at a corresponding distinct position on the display screen. The control unit is further configured to apply an adjustment offset to each orientation of the vertical adjuster such that each immediately vertically adjacent pair of beam footprints projected on the display screen resulting from the plurality of positions have a vertical overlap that is larger than a first threshold.

    摘要： A method for generating three dimensional (3D) displays. The method includes displaying a hologram that combines three (or more) images encoded into three (or more) different OAM channels, and the method also includes reflecting light from the displayed hologram to create a multichannel light beam. Then, the method involves decoding the multichannel light beam to decode and display the three encoded images. The decoding step includes displaying the three encoded images in decoded form in three view zones, three focal planes, or on three spaced-apart planes. The decoding is performed by a single decoding screen using holograms used for generating the three encoded images or is performed by three decoding screens configured based on a differing one of the holograms used for generating the three encoded images. The displaying of the hologram step includes operating a spatial light modulator (SLM) to display the hologram on a screen of the SLM.

    摘要： A projector using coherent light as a light source includes: one or more coherent light sources emitting coherent light beams; a beam scanner which changes a direction of the coherent light beam; and a beam splitter which splits a beam into multiple segments and changes a phase of light of each split segment, the beam splitter being located in an optical path between the beam scanner and the coherent light source. This projector reduces speckle noises. The beam splitter includes a pair of transparent substrates; a plurality of parallel electrodes disposed on each surface of the pair of transparent substrates, the pair of the parallel electrodes being disposed in a perpendicular direction to each other. Voltages are applied to the respective electrodes at predetermined time intervals so as to produce different potentials in a liquid crystal sandwiched by the transparent substrates.
