  • Multiple Laser Projection System
    Publication number: 20130162952
    Abstract: A method and apparatus for despeckling that includes a green laser diode, a DPSS laser, and stimulated Raman scattering light formed in an optical fiber. The laser diode light and stimulated Raman scattering light are combined to form a projected digital image. The output of the optical fiber may be split into two spectrums. The projected digital image may be stereoscopic with one image formed from the laser diode light and one spectrum, and the other image formed from the other spectrum.

  • Multiple Laser Despeckling
    Publication number: 20130107350
    Abstract: A method of despeckling that includes generating two pulsed laser beams, focusing both laser beams into an optical fiber, generating stimulated Raman scattering light in the optical fiber, and using the stimulated Raman scattering light to reduce speckle and/or change the color of the light. The time period between the peaks of the two laser beams may be controlled to adjust the amount of despeckling or color change.

  • Microbend-Enhanced Despeckling
    Publication number: 20130044367
    Abstract: A method and apparatus that enhances an aspect of light output from an optical fiber by microbending the optical fiber to increase stimulated Raman scattering light. The enhancement may be a change in speckle characteristics or a change in color. There may be an optical monitor that varies the amount of microbending by controlling the force on the optical fiber.
