  • Patent number: 7891818
    Abstract: A projection system that includes a singe light modulation device and a plurality of light sources of different wavelengths. Each wavelength of light is incident on the light modulation device at a spatially distinct location and a temporally distinct time. The use of a scanning mirror allows the projection system to sequentially form, in full-color, each of the columns or rows of an image. The projection system is characterized by the reduction of color separation or the rainbow effect due to the rendering of each column or row in full color.

  • Publication number: 20080259988
    Abstract: An optical actuator having an improved response time and an improved frequency operational range due to the reduced mass of a substrate coupled to an actuator and method of making the same. The optical actuator may be formed by adhering an uncoated substrate to the actuator using an epoxy. Once cured, any deformities and irregularities in a top surface of the substrate are removed. An optical coating is then applied to the top surface of the substrate. Once finished, the optical actuator may be used in a laser resonating cavity. Further, the optical actuator desirably may have a resonant frequency of about 150 kHz.

  • Patent number: 6868212
    Abstract: A method for adjusting the wavelength and dominant mode of a laser fiber prior to installation in a laser assembly includes the steps of linearly stretching the laser fiber so as to modify its output wavelength, axially twisting the laser fiber so as to modify its dominant mode, and affixing the laser fiber to a laser assembly in its linearly stretched and axially twisted condition. The laser assembly includes a dynamic tuning mechanism for wavelength adjustment during use. The twisted and stretched fiber has an unadjusted wavelength and dominant mode that are within a selected range before adjustment by the dynamic tuning mechanism.

  • Publication number: 20050007652
    Abstract: A microscopic optical structure controller for providing singular control of individual microscopic optical structures of a microelectromechanical optical device by a multiplexed stream of individual pixel values generated by a pixel value source. The microscopic optical structure controller includes at least one interconnect coupled to the pixel value source for receiving the multiplexed stream of individual pixel values and at least one mapper communicating with the interconnect for extracting individual pixel values from the multiplexed stream and applying the individual pixel values to one or more individual microscopic optical structures according to a configurable mapping. A method and a driver for providing singular control of individual microscopic optical structures of a microelectromechanical optical device are also disclosed.
