FMCW LiDAR vs. ToF LiDAR

This article compares Frequency Modulated Continuous Wave (FMCW) and Time of Flight (ToF) for LiDAR. In summary, FMCW is better in longer term but ToF is still better now. What are FMCW and ToF? Lidar can take on several different modalities, which can be classified by their dependence on incoherence or coherence of the laser…
