Alignment Analysis of Large Aperture RC System Based on Wavefront Aberration Test

通过对520mm口径RC系统进行面形波像差检测,并将其主、次镜各光学零件实际面形的干涉检测结果输入Code V软件进行了系统成像质量的波像差分析.分析结果与实际系统装调完成后的系统成像质量波像差检测结果对比,具有高度的一致性,说明在计算机辅助装调工艺中应用该仿真工具仿真度高,可以用于实际光学装调的仿真分析、指导光学装调.

Image quality analysis by CODE V software can obtain more accurate result of a main-secod mirror optical system based on each surface′s real wavefront aberration of surface error,and this result can be used to direct the alignment of the system.A 520 mm diameter RC system is analyzed,and the result is compared with real interferogram of surface error and non.It is shown that the former result is more close to the real wavefront aberration tested by a interferometer,which proves the feasibility and reliability of the proposed method used in optical alignment engineering.
