The Award database is continually updated throughout the year. As a result, data for the given year is not complete until April of the following year. Annual Reports data is a snapshot of agency reported information for that year and hence might look different from the live data in the Awards Information charts.

  1. Rapid Deposition of Uniform Thickness Fiber Interfaces in Bulk Fabric for CMC Toughening

    SBC: Physical Sciences Inc.            Topic: N08-148

    Physical Sciences, Inc. (PSI) will demonstrate the technical and economic feasibility of scaling up our method for applying uniform interphases to fibers within a woven fabric. During the Phase I program, we established that our self-limiting, scalable vapor phase deposition process can fabricate stoichiometric BN/Si_3N_4 interface coatings of consistent thickness using traditional CVD precursors ...

  2. Alternative Methods for Creating a Sodium Guidestar

    SBC: Hart Scientific Consulting International            Topic: AF17A-T005

    The objective of the proposed research is to demonstrate high-power, scalable, and stable laser sources at specific wavelengths with narrow linewidth matched to the single velocity class of mesospheric atomic sodium for guide star application. The operation at tailored wavelengths, 1141 nm and 1178 nm (for 589 nm via frequency doubling) is addressed by the use of bandgap-engineered optically pumpe ...

  3. Polychromatic guide-stars using novel optically pumped semiconductor disk lasers

    SBC: Crystalline Mirror Solutions, LLC            Topic: AF17A-T005

    During the last two decades, vertical-external-cavity surface-emitting lasers (VECSELs) have emerged as excellent high-power laser sources that combine diode-pumping, broad-pump tolerance, wavelength selectivity, narrow linewidth, broad tunability, high beam quality, compactness, and efficiency into one attractive package. These characteristics make them an ideal candidate for use as more economic ...

  4. Alternative Methods for Creating a Sodium Guidestar

    SBC: Arete Associates            Topic: AF17A-T005

    Adaptive Optics allow ground-based astronomical observatories to overcome atmospheric distortion limited observation by using natural and artificial guide stars to measure the distortion. Sodium-layer guide stars provide near all-sky coverage for high resolution astronomy. Over the last 20 years, Optically Pumped Semiconductor Laser (OPSL), also referred to as Vertically Extended Cavity Surface ...

  5. Alternative Methods for Creating a Sodium Guidestar

    SBC: TPhotonics Inc.            Topic: AF17A-T005

    The purpose of this proposed research is to develop and commercialize a novel two color sodium guidestar laser operating simultaneously at 589 nm and 1141 nm. Our patented T-cavity design combined with VECSEL technology will be the basis for the guidestar development. The polychromatic laser guidestar (PLGS) system being proposed currently does not exist and would allow for the correction of atmos ...

  6. Three-sided Pyramid Wavefront Sensor for High Sensitivity Wavefront Control

    SBC: Hart Scientific Consulting International            Topic: AF17A-T006

    Fully develop the analytic theory of wavefront reconstruction from measurements made with a three-sided pyramid wavefront sensor (PWFS3), including the effects of variable modulation, photon and camera noise sources, and object angular extent. Carry out performance predictions of the PWFS3 through numerical modeling. Compare the sensitivity of the PWFS3 to a conventional Shack-Hartmann sensor and ...

  7. Bayesian Inference of Spacecraft Geometry and Pose

    SBC: Vision Systems, Inc.            Topic: AF17A-T007

    Space platforms are complex dynamical systems and there are many reasons to model them from ground telescope imagery as well as from space-based sensor platforms. One key motivation is to determine the operational state and configuration of the vehicle. Key questions such as did the solar panels fail to deploy, did the object begin to tumble unexpectedly may be addressed by a sufficiently detaile ...

  8. Automated 3D Reconstruction and Pose Estimation of Space Objects Using Ground Based Telescope Imagery

    SBC: STELLAR SCIENCE LTD. CO.            Topic: AF17A-T007

    Stellar Science, in collaboration with the University of Maryland, proposes to develop algorithms to demonstrate the feasibility of constructing three-dimensional (3D) models of satellites using ground-based imagery on a standard PC in under 15 minutes. The Phase I effort will address the challenge of registering two-dimensional (2D) images of satellites where traditional feature matchers frequent ...

  9. Unified sensor for atmospheric turbulence and refractivity characterization

    SBC: MZA Associates Corporation            Topic: AF17A-T008

    MZA partnered with the Michigan Technological University (MTU) proposes to develop an atmospheric characterization sensor which unifies the measurement of atmospheric turbulence and refractivity through target-in-the-loop measurements, requiring no augmentation of the target or equipment on the other end of the path. We image multi-wavelength target illumination and remove atmospheric blurring us ...

  10. Target-In-The-Loop Sensing Suite for Long-Range Atmospheric Effects Characterization

    SBC: MV Innovative Technologies LLC (DBA: Opt            Topic: AF17A-T008

    This project offers a novel polychromatic target-in-the-loop atmospheric sensing (TILAS) concept for in situ characterization of the combined effects of atmospheric turbulence, refractivity, transmittance, and optical path difference (piston phase) over long-range, low elevation angle atmospheric paths. The proposed concept allows practical implementation of a modular compact TILAS atmospheric sen ...
