N2 - This thesis studies the stitching interferometry of large aperture optical aspheric surface. Analyzing the data of the adjacent two sub apertures overlap by using SIFT algorithm, we obtained the stitching parameters between the sub-aperture and the overall surface information of the inspected mirror. We wrote the interference graph solution phase program, Zernike fitting program, stitching test program, and completed the principle experiment. We have given the compare results of stitching and full caliber testing, the RMS deviation of the two kinds of method is less than 2nm. Keyword: Large aperture optical aspheric surface; subaperture stitching; Zernike fitting; Interference measurement;
