Figure | The schematic of the proposed FMCW LiDAR monitoring system.  a, The basic configuration of the LiDAR monitoring system. b, The frequency relationship of the LO beam and probe beams reflected from different devices, which will generate beat signals of different frequencies and carry the reflection spectra information. c-e, The signal demodulation process, the beat signals are separated in spatial domain by FT and then the reflection spectra are reconstituted in wavelength domain by IFT.
