英文摘要	Aspherical optical elements bring much benefit to modern optical systems, due to its significant role in improving optical performance by compensating residual aberrations, and decreasing system's weight. However, manufacturing aspherical surfaces in high accuracy is usually limited by the ability of surface metrology, especially for convex aspherical surfaces. In this paper, we propose a compensating stitching method combining computer generated hologram (CGH) compensating testing and stitching testing to achieve the full aperture map of convex aspherical surfaces. Firstly, we introduce our self-developed mathematical models in the compensating stitching method, including CGH design model, subapertures' alignment model and stitching model. Then the performance of our proposed method is demonstrated with compensating stitching testing of an off-axis convex aspherical mirror with its aperture of 332mmx144mm. The experimental result shows that the convex aspherical surface can be tested in full aperture with our proposed method effectively, which demonstrates that our proposed surface testing method opens a new path for the testing of convex aspherical surfaces.
