FMCW LiDAR Using Dual Interferometer for Improving Distance Measurement
Frequency-modulated continuous wave (FMCW) system was implemented using dual interferometers with two different optical delay lengths. This system can overcome the limitation of the distance measurement range due to the coherence length of the light source.
