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.
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: A dual-comb measuring system is provided. The dual comb measuring system may include a bi-directional mode-locked femtosecond laser, a high-speed rotation stage, and a fiber coupler. The high-speed rotation stage may be coupled to a pump diode.
