摘　　要：为了使光学仪器能在恶劣的环境下正常工作,需要对其进行详尽的工程分析。对光机系统的分析方法,包括传统分析方法、集成分析方法和统一分析方法进行了研究,说明了它们的工作原理及实现的具体步骤,分别列举了它们的优缺点。进一步指出在集成分析中热弹性分析需要解决的问题及Zern ike多项式拟合中需要注意的问题,归纳了使用统一分析方法时需要特别注意的问题。在比较了3种方法优缺点的基础上,对光机分析方法进行了展望,得出集成分析方法在很长一段时间内将是光机系统分析的主要方法的结论。In order to ensure the proper operation of optical instrument in harsh environment,detailed engineering analyses are frequently needed.Traditional analysis,integrated analysis and unified analysis for opto-mechanical systems were investigated.Their operation principles,processes,as well as their advantages and disadvantages are described.Some issues on thermal-elastic analysis and the fitting of Zernike polynomial in integrated analysis are addressed.The problems need to be considered in unified analysis are summarized.Based on the tradeoff investigation of the three methods,the development trend of the opto-mechanical analysis methods is forecasted.It is concluded that integrated analysis is the most frequently used opto-mechanical analysis method in the long run.
