Sub-aperture stitching testing technique extends lateral and vertical dynamic range of interferometer. The large-aperture optical components can be tested by this technique with low cost and high resolution. According to the differences of sub-aperture shapes, the working principles are outlined, respectively. Meanwhile, several representative stitching algorithms are introduced. The domestic and overseas development history and status are reviewed. Based on the analysis and comparison of them, the development trend and application prospect of this technique are pointed out in the end.
