    Abstract: A refractive spatial heterodyne spectrometer includes an input aperture for receiving an input light; a collimating lens for collimating the input light into a collimated lightbeam; and a beamsplitter for reflecting one part of the collimated light into a first arm and transmitting another part of the collimated light into a second arm. The first arm includes a first dispersing prism for receiving and refracting the first part of the collimated light, and a first mirror positioned to reflect the refracted first collimated light back through the first dispersing prism and to the beamsplitter as a first light wavefront. The second arm includes a second dispersing prism for receiving and refracting the other part of the collimated light, and a second mirror positioned to reflect this refracted light back through the second dispersing prism and to the beamsplitter as a second light wavefront. The beamsplitter transmits a portion of the first light wavefront and reflects a portion of the second light wavefront into an output optics section to inferometrically combine into an interference image, and a detector receives the interference image and outputs an interference image pattern.

    Abstract: An orbital debris detection system positionable on a satellite launchable into an earth orbit includes a light source having a collimated light output, a curved mirror for receiving the collimated light output and forming a light sheet outside the satellite, and a scattered light detector for detecting a scattered light from the light sheet resulting from orbital debris intersecting the light sheet and scattering light toward the detector. The system can provide damage attribution on a space vehicle (whether it was just hit by a piece of debris), data gathering for debris models (time, location, approximate debris size, direction of trajectory) that are starved for information on small (

    Abstract: Obtaining global tropospheric vertical wind profiles by directly detecting atmospheric winds using space borne, airborne and/or ground station platforms is accomplished by a DASH interferometer in the back-end of a Doppler wind LIDAR. In the front-end of the Doppler wind LIDAR, a laser illuminates an atmosphere and a telescope collects backscattered laser light return signals from the laser illuminated atmosphere. The DASH interferometer processes return signals from the atmosphere, forming an interferogram and determines from the interferogram a Doppler shift of the return signals, which is equivalent to determining the line of sight wind speed of the Doppler wind LIDAR observation, by measuring the frequency shift caused by winds. From this determination, global and/or non-global atmospheric wind profile data are transmitted over a communications network in either real-time and/or non-real-time, to facilitate weather forecasting, weather modeling, weather avoidance navigation, atmospheric research, hurricane warnings, operations systems selections and deployment of operational assets.
