  • Patent number: 10466455
    Abstract: High resolution printing systems that utilize high power laser diode bars and digital mirror devices (DMD) require side-by-side stacking of illumination modules to stitching of the image from each module to form a longer total image width. An inline illumination optical system having a refractive prism and Total Internal Reflection (TIR) prism pair with an air gap along with a light guide transporting light beams at a compound angle to the prism pair eliminates the need for any axial rotation of the laser and light guide, and enables side-by-side module stacking. The illumination optical system includes an illumination module having a light source, the light guide, a DMD array and a Refractive TIR (RTIR) prism. The system also includes a DMD housing containing the DMD array and having a width within which the illumination module is confined to allow side-by-side stacking.

  • Publication number: 20150070741
    Abstract: Optical systems are provided that include illumination sources, micro-mirror array optical modulators, and an optical element. The micro-mirror array optical modulators can selectively modulate light beams, redirect light by diffraction and reflection, and provide an output modulated light beam that exhibits a diffraction handedness dependent on the spectral bandwidth of the light incident thereupon. The optical element has a color dependent aperture that defines portions of output modulated light beams that are transmitted and remaining portions that are blocked. An efficiency and contrast of each the output modulated light beams acquired by the optical element can be independently determined by a narrow spectral bandwidth of each of the light beams, the spectral characteristics of the color dependent aperture, and the diffraction handedness of the micro-mirror array optical modulators for the associated spectral bandwidth.

  • Patent number: 8976318
    Abstract: A method and system for zonal switching for light steering to produce an image having high dynamic range is described. The system comprises: a light source for providing light along an optical path; a spatial light modulator for directing portions of the light to off-state and on-state light paths, thereby producing an image, the spatial light modulator having a plurality of illumination zones corresponding to the image; and a set of sequentially-arranged optical elements in the optical path for steering at least some of the light from a first subset of the plurality of illumination zones to a second subset of the plurality of illumination zones to increase the dynamic range of the image. The dwell time of the one or more sequentially arranged optical elements can be modified to steer light.

  • Patent number: 8970939
    Abstract: A multi-state light modulator comprises a first reflector. A first electrode is positioned at a distance from the first reflector. A second reflector is positioned between the first reflector and the first electrode. The second reflector is movable between an undriven position, a first driven position, and a second driven position, each having a corresponding distance from the first reflector. In one embodiment, the three positions correspond to reflecting white light, being non-reflective, and reflecting a selected color of light. Another embodiment is a method of making the light modulator. Another embodiment is a display including the light modulator.

  • Patent number: 8905553
    Abstract: A method of detecting a scanning angle range of a laser beam of a laser projector is provided. First, a photo sensor is disposed between first and second positions on a projection mirror. Then, a laser beam emitted from the laser projector scans back and forth between the first and second positions, so that the photo sensor receives the laser beam sequentially at first and second scanning time points to generate first and second sensing signals, respectively. If an actual time interval between the first and second sensing signals conforms to an expected time interval, an actual scanning angle range of the laser beam is determined as normal. If the actual time interval does not conform to the expected time interval, the actual scanning angle range of the laser beam is determined as abnormal and the laser projector stops emitting the laser beam. A laser projector is also provided.
