Estimation Method for Maximum Range of Laser Ranging System

Maximum range is one of the important parameters which can reflect the laser measure system´s performance. How to measure and evaluate the maximum range has become an important study. This paper analyzes the range measure capability of laser ranging system firstly, then the influence on range measure capability by optics axis error, atmosphere and background noise are debated. Finally, a novel method which can estimate the maximum range of laser ranging system is proposed. Experimental results show that the maximum range of the pulse laser range finder can be measured accurately by this method, and it has high accuracy, repeatability and serviceability. The estimation of maximum range can provide the distance reference for the outdoor test, and to heighten the test efficiency, which will be useful for the test of laser measure system.
