Measurement and test technology of laser tracking and ranging

This paper describes a error slope curve measurement system for laser tracking.The system is composed of a semiconductor laser source,an array laser beam intensity distribution measurement instrument and a interface for data collecting and processing of laser tracking and ranging etc.The measurement accuracy of the system is high up to second grade.So,it becomes a main support method for measurement and test of laser tracking and raging equipment assembly,and give out the results of error slope curve.
