8. Influence Factors of Measurement

8.1 Multi Optical Path

Based on ToF LiDAR principle, if there are multiple echo regions as shown in the figure below at the

working height of the radar, the multi-path phenomenon will be triggered: the LiDAR receives the light

returned by the path 1 and the path 2 at the same time, which may result in a larger measurement value.
