  • Publication number: 20200003879
    Abstract: A laser ranging system includes a light source emitting a beam of collimated light. A beam splitter polarizes the beam with a first type of linear polarization. A wave plate receives the beam from the beam splitter and polarizes the beam with a circular polarization. A movable mirror scans the beam across a target, receives a return beam from the target, and reflects the return beam toward the wave plate. The wave plate polarizes the return beam with a second type of linear polarization. The beam splitter receives the return beam from the wave plate. A detector detects arrival of the return beam from the beam splitter. A circuit receives determines a distance to the target as a function of a time interval between emission of the beam and arrival of the return beam.
