Based on the detailed analysis of the Zernike aberrations of wavefront errors,including the wavefront defocus and tilt,introduced by test surface misalignment in the high-precision spherical surface testing,a method for the misalignment calibration using Zernike coefficients was put forward in this paper.The experimental validation of the proposed calibration method was carried out with Zygo interferometer,in which a high-numerical-aperture spherical surface was tested by introducing both the wavefront defo...
