Analysis and control on assemblage tolerance in small-aperture high-precision refractive optical system
-
摘要: 采用小口径高精度折射式光学系统的对地观测遥感器对成像质量要求严格，随之对装调公差要求苛刻。传统装调公差分配完全以光学设计给定公差为标准，在实际装调过程中与精度和周期的需求产生矛盾。提出将光学设计和装调实践相结合，用全过程仿真计算进行成像质量预估，对公差进行再分配，并利用光学系统各分离误差相互间的补偿，实时调整公差。然后举例说明在某小口径高精度折射式光学系统装调过程中对公差的具体分析，并详细阐述了针对公差的再分配和补偿方法，实现对偏心误差的控制精度为2，对镜间距的控制精度为1 m。镜头装调完成后成像性能良好，证明公差分配及控制方法的改进使装调效率显著提高。Abstract: High imaging quality is required in the small-aperture high-resolution space-to-ground remote sensor of refractive system，as a result the assemblage tolerance is rigorous. The assemblage tolerance distribution rooted in optics design before, however, the strict tolerance cannot be achieved in smallaperture high-resolution space remote sensor now. An improved tolerance distribution was recommended based on the combination of optic design and assembly practice.It estimated the imaging quality through the emulation of whole process, reallocated the tolerance and adjusted it by compensation realtimely . The improved tolerance distribution was proved by a small-aperture camera lens assemblage.Results show that the control accuracy of eccentric error is 2,and that of mirror spacing is 1 m,the imaging quality is good after camera assemblage.
