    Abstract: A frequency modulated continuous wave LiDAR system is disclosed that may be scalable and integrated in compact and demanding environments. The improved system of the present disclosure includes: an electro-optic modulator configured to modulate a laser generated by a laser source; a balanced photo detector configured to process an interference signal of a local copy of the laser coupled with a signal of the laser returned from a target and output a beatnote signal; a modulation source with two outputs, and a Frequency Information Rapid Extraction for Ranging Applications (“FIRE-RA”) system to receive the interference signal from the balanced photo detector, process the interference signal with a signal from one of the two outputs of the modulation source for the balanced photo detector, and output distance and speed data for the target according to the processed interference signal.

    Abstract: Computing systems, methods, and non-transitory storage media are provided for obtaining a signal emitted from a Lidar, applying a frequency modulation to the signal to generate an up-scanning direction and a down-scanning direction of the signal, wherein the up-scanning direction and the down-scanning direction are symmetric, suppressing a carrier frequency of the signal in response to the applying of the frequency modulation, applying a frequency modulation to the carrier frequency by shifting a local oscillator to change a symmetry between the up-scanning direction and the down-scanning direction, or adding a phase modulation, directing the signal to a target, and simultaneously determining a velocity and a direction of motion of the target with respect to the Lidar based on frequencies of a reflected signal from the target in the up-scanning direction and in the down-scanning direction.

    Abstract: A laser source generates an optical signal. A splitter splits the optical signal into a first signal and a second signal. A first modulator modulates the first signal. A second modulator modulates the second signal. A scanner scans the first signal following the modulation by the first modulator. A coupler combines the modulated second signal and the modulated first signal following the scanning of the first signal. A detector detect an attribute corresponding to the combined modulated second signal and the modulated first signal and captures a target based on the combined modulated second signal and the modulated first signal.
