A new method is proposed for testing standard quadric surfaces with several subapertures based on interferometry. Subapertures arrangement, best-fit sphere calculation and distortion correction about such surfaces are discussed in this paper. In addition, we provide an experimental demonstration by testing a Ø310 mm convex hyperboloid mirror. The experimental result shows that the proposed method can accomplish the testing of quadric mirrors without auxiliary compensation effectively. The analysis and proposed methods bring much to the application of non-null aspheric testing.
