To test the ultra-deep conic surface in wide-field optical systems, a catadioptric null test method is researched in this paper. Equations of infinite conjugate null test system are established and solved using optical path length. The numeric results of a self-aligning mirror's shapes are fitted by coefficients and validation is done in optical design software. The rms wavefront error is 0.0019λ (λ=632.8 nm) in the example fitted by five coefficients. Furthermore, by adjusting spherical aberration distributions, an all-spherical finite conjugate null test system is designed, whose rms wavefront error is 0.0309λ. The test methods in this paper have been proven to be adaptive to many other similar ultra-deep surfaces, even with higher orders.
为了测试宽视场光学系统中的超深圆锥面，本文研究了一种折反射零位检测方法。利用光程建立并求解了无限共轭零位检测系统的方程。通过系数拟合自准直镜形状的数值结果，并在光学设计软件中进行验证。在由五个系数拟合的示例中，均方根波前误差为0.0019λ（λ=632.8nm）。此外，通过调整球差分布，设计了一种全球面有限共轭零位检测系统，其均方根波前误差为0.0309λ。本文中的测试方法已被证明适用于许多其他类似的超深表面，甚至是高阶表面。
