Abstract

A method to test an off-axis parabolic (OAP) mirror at fine grinding stage using CMM (coordinate measuring machine) is introduced in this paper. Tilt error and the probe radius error have been removed as a system error before interpolation. An interpolation method, which based on Tikhonov regularization, is used to fit surface error. An example, which shows the effectiveness of this method, is also given.
