  • Methods and apparatus for phased array imaging
    Patent number: 10571569
    Abstract: A method of imaging a scene includes generating a temporally varying optical intensity pattern from at least one continuous wave (CW) light beam. The method also includes illuminating at least one portion of the scene with the temporally varying optical intensity pattern so as to cause a photon to scatter or reflect off the at least one portion of the scene. The photon reflected or scatted from the at least one portion of the scene is detected using a single-photon detector. Based on the temporally varying optical intensity pattern and a time of flight of the photon detected, a distance between the single-photon detector and the at least one portion of the scene is estimated.
    Type: Grant

    Date of Patent: February 25, 2020
    Assignee: Massachusetts Institute of Technology
    Inventors: Juan C. Montoya, Antonio Sanchez-Rubio, Harold C. Payson, Robert E. Hatch, Richard Heinrichs, Dale G. Fried
