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.
Claims1
A dual-sideband frequency-modulated continuous-wave (FMCW) LiDAR system comprising:
- a modulated light generation unit, comprising:
- an electro-optic modulator configured to modulate a continuous wavelength diode laser carrier to simultaneously generate an up-chirped sideband and a down-chirped sideband;
- a fiber coupler configured to split the up-chirped sideband and the down-chirped sideband into a first split light beam and a second split light beam;
- and
- an optical amplifier configured to generate a boosted light beam from the first split light beam;
- a transceiver unit configured to receive the boosted light beam, direct the boosted light beam to a region of interest, and receive a received signal reflected from the region of interest;
- and
- a control and processing unit comprising a balanced photodetector (BPD), a DAQ card, a processor, a waveform generator, and a signal generator.
