Abstract

The aspheric surfaces can be tested by using interference type computer-generated holograms (CGH). However, the measurement results are affected by the system errors that exist in optical arrangement. In order to improve the test accuracy, a quantitative method for processing the system errors has been investigated. Experimental results show this method is feasible and effective.
