小口径反射式光学系统装调方法研究分析

在红外光学装调系统中,镜片间距是需要精密控制的重要装调参数。由于反射镜在红外光学系统中通常为折转光路,传统装调方法无法直接应用,所以高精度光学系统一直着重关注折转光路中距离的装调方法。文章提出了两种折转光路距离的装调方法,即接触式装调与非接触式装调。针对这两种装调方法,使用了小口径反射镜进行了实例验证。并对比两种装调方法的结果,分析得出两种装调方法的优劣性。

Research and analysis on the installation and adjustment method of small aperture mirror

In infrared optical adjustment system,the lens distance is an important parameter that needs to be precisely controlled.Since the mirror is usually used in infrared optics as a folding path,traditional decoration methods cannot be directly applied,so the high precision optical system has been focusing on the adjustment method at mid distance from folding path.In this paper,two methods of mounting for folding the optical path namely contact type adjustment and non contact adjustment are proposed.The two adjustment methods are verified using small aperture mirrors.The results of the two methods are compared,and the advantages and disadvantages of the two installation and adjustment methods are analyzed.
