  • Publication number: 20130003343
    Abstract: A system is provided having a multiplexed laser source which combines the outputs of multiple lasers into multiplexed illumination which is then externally modulated to provide output illumination having reduced or zero speckle. Each of the laser sources are turned ON and OFF (gated) in a timed sequence to provide multiplexed illumination having a time-averaged speckle contrast that is lesser than the speckle contrast of the output of any one of the lasers. The output of one or more lasers may also be wavelength multiplexed, where the lasers operate at different wavelengths, and/or polarization multiplexed. An external modulator receives and modulates the multiplexed output in phase and/or modal power distribution to further reduce the speckle in the output of the system. The multiplexed laser source and external modulator can be used as separate apparatuses for reducing speckle in laser illumination.

  • Patent number: 8300219
    Abstract: Methods and apparatuses are provided that can be utilized for accurate pre-aiming and installation of devices. The devices are pre-set to an aiming orientation relative to a universal reference plane. The reference plane is then correlated to a feature of a pole, tower, or other structure that will be used to elevate or suspend the devices. A position sensing subsystem is utilized to inform a worker when each device is correctly angularly oriented to the reference plane. The worker simply moves the mounting structure for the device to the correct three-dimensional angular orientation, uses the position sensor to confirm the correct orientation to within a highly accurate margin of error, and either locks the device in that orientation or marks the orientation. The pole, tower, or other elevating structure is then preliminarily erected at its pre-designed location and pre-designed rotational orientation with the pre-aimed devices.

    Abstract: A system for equalizing pulse to pulse energy of a light beam includes a group of optical devices including an optical device configured to exhibit nonlinear properties, e.g., higher order or third order nonlinear properties. Transmission properties of an unequalized light beam passing through the group of optical devices change such that an output intensity of a resulting light beam output from the optical devices is equalized. One example configuration includes at least first and second prisms having nonlinear properties, i.e., higher order or third order, and configured as a beam steering system.

  • Publication number: 20120140476
    Abstract: [Objective] To restrict degradation of optical characteristics due to a resin adhesive containing an inorganic filler. [Means] The width d of a lens body 31 and the height of an inorganic filler 341 in a direction orthogonal to the surface of a substrate are set such that an inclination angle of a collimating lens 3 does not exceed a maximum tolerable inclination angle when the inorganic filler 341 is positioned near the width-wise center of the lens body 31. As a result, even when the inorganic filler 341 is inserted between the bottom surface of the collimating lens 3 and the top surface of the substrate 4, degradation of the optical characteristics of the laser module including skewing of the optical axis of the laser light and distortion of the beam shape of the laser light can be restricted.

    Abstract: A light source is provided. The light source includes: an elliptical reflection mirror having first and second focal points; a discharge chamber in which a luminescent substance is enclosed and which is disposed on the first focal point; a laser light generator which emits the laser light; and a laser light guide which guides the laser light from an opening side of the elliptical reflection mirror into the discharge chamber. The luminescent substance is excited by providing the laser light to the luminescent substance so as to emit light, and the light is reflected by the elliptical reflection mirror. The laser light guide is disposed in a shade area in which the light reflected by the elliptical reflection mirror is blocked by the discharge chamber.
