A Method for Maintaining the Stability of Range Walk Error in Photon Counting Lidar with Probability Distribution Regulator

Photon counting Lidar applied to long-distance ranging will face the problem of the number of received photons fluctuating with target distance and reflectivity. The Poisson probability model indicates that the range walk error of the system fluctuates with the number of received photons, which deteriorates the performance of ranging. We propose a novel approach based on the probability distributi...
