Abstract

The methods of surface irregularity testing and characteristic parameter measurement for aspherical mirrors are studied experimentally and computer-simulatively. An accurate method for paraxial curvature radius measurement of aspherical mirrors by a special micrometric rod, in the meantime of testing of surface irregularity, is described. Finally, the measurement accuracy is analyzed.
