摘要 针对Offner成像光谱仪同心系统三个离轴放置的反射镜组成的系统,从光学成像质量分析出发,分析三个镜面面型、几何尺寸误差以及安装位置误差范围。利用Patran和Nastran软件分析与建模,分析该系统的静力载荷及模态响应,同时利用热光学理论研究镜片支撑与结构方案,从而开展分设计系统的结构布局:支撑方案和结构形式,更科学的评估Offner成像光谱仪结构设计的合理性。 In this paper, in order to research the system that consists of three off-axis reflectors of Offner Imaging Spectrometer concentric system, three mirror face, geometrical dimension error and installation position error ranges were analysed, based on optical imaging quality analysis. Using Patran and Nastran software analysis and modelling, the static load and modal response of the system were analysed, while the theory of thermal optics was used to investigate the lens support and structure scheme, so that the structure layout of the design system was carried out: support scheme and structure form, and more scientific estimation on the rationality of the structure design of Offner imaging spectrometer
