Abstract

The aspheric surfaces can be tested with using the interference type computer--generated holograms (CGH). However, the system errors which exist in optical arrangement affect the measurement result. For this reason, this paper proposes a new method using CGH to compensate the system errors, in which Zernike polynomial analysis and calculation are applied. The method is verified by experiment.
