  • Low etendue illumination
    Patent number: 10678061
    Abstract: An optical system and method that utilize multiple low-etendue lasers to illuminate multiple spots one or more spatial light modulators. Stereoscopic systems may be formed by using different wavelengths or different polarizations for each spot. Light from each spot is guided to each eye of the viewer by wearing 3D glasses.
    Type: Grant

  • Despeckling Apparatus and Method
    Publication number: 20140111847
    Abstract: An apparatus and method that reduces laser speckle by using stimulated Raman scattering in an optical fiber. The fiber core diameter and length are selected to achieve a desired output color. An adjustable despeckler is formed by combining two optical fibers in parallel and adjusting the amount of light in each path.

  • Short Pulse Despeckling
    Publication number: 20130278903
    Abstract: An apparatus and method for despeckling that includes a pulsed laser with a pulse width between 1 ps and 10 ns and stimulated Raman scattering light formed in an optical fiber. The stimulated Raman scattering light may be used to form a projected digital image. A second pulsed laser with a wavelength at least 2 nm different may be included and stimulated Raman scattering light formed in a second optical fiber may be combined with the stimulated Raman scattering light formed in the first optical fiber.
