  • Multifrequency ocean lidar power optimizer
    Patent number: 10819082
    Abstract: Systems and methods are provided for optimizing the energy output of a laser system, such as a Light Detection and Ranging (LIDAR) system, by allowing the laser system to be tuned while the laser is in operation. For example, in an embodiment, a sensor, such as a photoresistor, is used to perform a scan to determine whether turning the crystal will result in increased energy. Crystal turners, such as servo motors, can be used to turn the crystal until the energy stops increasing.
    Type: Grant
    Filed: July 26, 2019
    Date of Patent: October 27, 2020
    Assignee: The Government of the United States of America, as represented by the Secretary of the Navy

  • Turbulence ocean lidar
    Patent number: 10094928
    Abstract: Embodiments relate to characterizing underwater turbulence. Initially, multispectral laser light (MLL) is generated and then converted to output laser light (OLL). The OLL is received at a polarization rotator that causes the OLL to be emitted in one of multiple modes of polarization. Next, the OLL is directed toward a target medium, where the OLL causes backscattered light to be emitted from the target medium. While using the polarization rotator to switch between the multiple modes of polarization, Stokes parameters of the backscattered light are detected and then used to characterize the underwater turbulence of the target medium.
