Frequency-modulated continuous-wave laser ranging beyond the limits of bandwidth and phase noise

APL Photonics
Frequency-modulated continuous-wave (FMCW) laser ranging typically applies an interferometer and linear frequency-modulated (LFM) signals to measure the distance, in which precision and resolution are limited by the phase noise of laser and the bandwidth
