To accomplish the subaperture stitching testing for flat mirror under considerable adjustment error, we established a reasonable stitching algorithm and mathematical model based on iterative gradient algorithm. At the same time, a Φ150mm flat mirror stitching experiment was taken to demonstrate the performance of the stitching algorithm. The surface maps were consistent between the testing results before and after stitching with the PV and RMS deviation 0.022λ and 0.003λ respectively.
