In order to measure the performance parameters of laser range finders, a new intelligent measuring system is developed, which introduces advanced control technologies, very quick and convenient WIN32 computer software and a skillfully designed beam splitter system. It can synchronously measure optical axis consistency, width and energy of the pulse, beam divergence angle, and so on. A 1296×1030 CCD is adopted in order to ensure 10″ of spatial resolving ability;A 350MHz oscilloscope is used to catch the laser pulse as narrow as 10ns;A laser power meter which has high accuracy and large dynamic scope is used to obtain accurate energy measurement of the laser pulse. The system has been checked and accepted, and all the performance parameters meet the design demands. Now it is used by user and operates very well.
