A Study into Laser Pulse's Impact on the Precision and Accuracy of the Diffuse Laser Ranging System

Ranging precision and accuracy are important parameters for laser ranging system. These factors are associated with laser pulse width, strength of echo wave and noise. So numerical modeling analyzing the relationship among them is established. The Ranging precision and accuracy are analyzed mainly with single, multiply photon and under different pulse width conditions. Some reference foundations are provided for improving ranging precision and accuracy of the diffuse laser ranging system so as to choose laser and optimize the way of observation.
