Abstract

To realize the fast, efficient alignment of Cassegrain system, the scheme of computer-aided alignment is proposed. The misalignment state of Cassegrain system was simulated in Zemax, corresponding relationship between the misalignments and Zernike polynomial coefficients is analyzed and the misalignment characteristics of Cassegrain system were summarized by Matlab. Finally, the alignment scheme is determined by analysis. In order to verify the scheme, the Cassegrain system was aligned according to the value which was calculated in accordance with the alignment scheme. The result demonstrates that the alignment scheme is feasible to Cassegrain system. Satisfactory results are achieved in applying the scheme of computer-aided alignment to the alignment of 1.2m and 1.8m telescopes.
