Abstract

Complex optical system, especially the all-reflecting off-axis spherical system is developed and used in the remote sensing camera and the UVX lithophotography. The alignment becomes more important to such system. In this paper, a computer-aided alignment method is described. The wavefront errors are obtained by using the autocollimating interferometric test at some field of views. A serial of aberrations explained by the coefficients of Zernike polynomials is gotten. They are the object values and will be corrected. The least square method is used to determine the misalignments. This method is demonstrated by the results of numerical simulation. The practical experiments are also given.
