  • Multi-emitter image formation with reduced speckle
    Publication number: 20080095203
    Abstract: A technique for reducing speckle in a projected image includes forming an image using a plurality of laser light emitters. An input to the plurality of laser light emitters is non-mechanically perturbed to a degree sufficient to disrupt wavefront uniformity across the array of laser light emitters.

  • Composite material with powered resonant cells
    Patent number: 7205941
    Abstract: A composite material and related methods are described, the composite material being configured to exhibit a negative effective permittivity and/or a negative effective permeability for incident radiation at an operating wavelength, the composite material comprising an arrangement of electromagnetically reactive cells of small dimension relative to the operating wavelength. Each cell includes an externally powered gain element for enhancing a resonant response of that cell to the incident radiation at the operating wavelength.
