基于像差校正的望远系统装调方法研究

为了保证望远镜装配完成后的成像质量和其他关键指标，提出基于像差校正的望远镜装调方法。首先利用Zemax建立光学系统模型，模拟光学零件失调状态，分析各零件的每种失调状态对各类像差的影响情况，进而定量计算光学零件对系统像差的敏感矩阵，得出系统失调特性，拟定最佳装调方案。在此理论分析的指导下，进行基于星点检验法的装调实验，装调后仪器各项指标达到要求，分辨率优于技术指标要求7.5，验证了基于像差校正的光学系统装调方案的可行性。

Assembly and adjustment method based on aberrations correction for telescope optical system

In order to ensure the imaging quality of certain type telescope at assembly stage, an alignment method based on aberrations correction was proposed. The optical system model of this telescope was set up and the misalignment phenomena for every optical element was simulated to analyze the changes of aberrations, then the sensitivity matrix of optical element for aberrations was calculated and the best alignment scheme was determined to improve the assembly quality and efficiency.Finally the alignment experiment based on star test was conducted, the results show that the technique indicators are all satisfied after alignment and the resolution is better than required 7.5,which could validate the feasibility of our method and offer operability for the assembly and adjustment of this kind of instrument.
