LiDAR: FMCW - The future of LiDAR?

Eye safety concern

Moreover, today’s time-of-flight lidar systems operate at 850 nanometer and 905 nanometer wavelengths, which are very close to the visible spectrum.

Frequency modulated continuous wave of the future

Coherent lidars, based on the frequency modulated continuous wave, or FMCW, technique allow much higher detection sensitivity and accuracy. For FMCW lidar, the signal-to-noise ratio is proportional to the total number of transmitted photons and not to the peak laser power. Since FMCW lidar has more than 10 times greater sensitivity, it can transmit at less than 1,000 times lower average power than pulsed time-of-flight lidar.

Advantages of FMCW vs ToF

There are several other advantages worth highlighting using FMCW vs. ToF lidar:
