| 中文摘要 | Surface irregularity of optical elements is one of the errors caused in manufacturing process. The primary aberration caused by surface irregularity is astigmatism which can hardly be removed in traditional alignment method. An alignment method by rotating the lens for compensating the deterioration of the image quality caused by surface irregularity is put forward in the paper, and the mathematical model of the method is established. The calculation of the rotate angle is described in detail. A numerical simulation of the method has been performed for a four-lens precision optical system to verify the ability and accuracy of the method. The results show that the astigmatism of the optical system caused by the surface irregularity can completely be removed, and the image quality can be improved effectively. The method is especially suitable for the optical system which demands a very high image quality. |
