  • Patent number: 10962409
    Abstract: The invention discloses a method and system for measuring orbital angular momentum modes of photons based on spiral transformation. A phase plate located in an input plane transforms the incident beam along a spiral path in the input plane into a straight line in an output plane and a phase plate located in the output plane compensate the phase accumulated when the beam propagates from the input plane to the output plane during the above transformation process, thereby realizing that the orbital angular momentum modes of photons to be measured in the input plane are transformed into plane wave modes with specific tilted wavefronts in the output plane. The plane wave modes with different tilted wavefronts can be focused on different positions on the focal plane and thus realize one-to-one mapping and detection between orbital angular momentum modes of photons and spatial locations.

    Abstract: The invention relates to a method and a device for determining a return time of a returning light pulse by a Single Photon (SPL) LiDAR scanner, the SPL scanner comprising of a low photon count detector for converting low amounts of photons or single photons to electrical signals, and a control and processing unit for processing the data and for determining the return time of the returning light pulse. The control and processing unit identify detected photons potentially representing a return pulse event and create a return pulse signal based on a criterion involving a temporal probability distribution for the detected photons, identify a rising edge and a falling edge of the return pulse signal, and determine the return time for each return pulse event based on the rising edge and the falling edge of the return pulse signal.
