  • Chip-scale star tracker
    Patent number: 9891305
    Abstract: A chip scale star tracker that couples starlight into a lightguide such that the angle of incidence partially determines the mode of propagation of the starlight in the lightguide. A baffle system integrated with the lightguide prevents propagation of light incident from a predetermined range of angles.
    Type: Grant
    Filed: June 3, 2016
    Date of Patent: February 13, 2018
    Assignee: THE CHARLES STARK DRAPER LABORATORY, INC.
    Inventors: Juha-Pekka Laine, Gregory P. Blasche, Murali V. Chaparala, Robin Dawson, Benjamin Lane, Stephen P. Smith, Erik Waldron

  • Chip-scale star tracker
    Patent number: 9372250
    Abstract: A chip scale star tracker that captures plane-wave starlight propagating in free space with a wafer-thin angle-sensitive broadband filter-aperture, and directs the light into a waveguide structure for readout. Angular information about the star source is determined from characteristics of the starlight propagating in the waveguide. Certain examples include internal propagation-constant-based baffling to elimination stray light from extreme angles.
