Abstract
A lidar system includes a laser source, a photodetector, an emission lens, a receiving lens, and a processor. The laser source is configured to be translated through a plurality of emission locations, and to emit a plurality of laser pulses therefrom. The emission lens is configured to collimate and direct the plurality of laser pulses towards an object. The receiving lens is configured to focus the portion of each of the plurality of laser pulses reflected off of the object to a plurality of detection locations. The photodetector is configured to be translated through the plurality of detection locations, and to detect the portion of each of the plurality of laser pulses. The processor is configured to determine a time of flight for each of the plurality of laser pulses from emission to detection, and construct a three-dimensional image of the object based on the determined time of flight.
