| Abstract: | A method based on double-beam principle is proposed to cope with testing reflective of optics by the measuring beam going alone the path of "VW".This proposed method needs an extender to have the measuring beam extended,so that the reflective of optics can be tested by large measuring beam.According to this method,a measurement system is constructed,and its accuracy and repeatability are analyzed by testing a standard absorption glass.A reflecting mirror used in the Inertial Confinement Fusion System is tested by this system to compare with the result of lambda 900.The results show that the reflective accuracy of the system is 0.1%. |
