利用激光的优点,研制了一种操作方便、用途广泛、精度高的偏振激光多用干涉仪。仪器采用了1/4波片、偏振分光镜系统,能调节干涉条纹反差和消除光学系统各表面剩余反射的影响。主要介绍了仪器的设计思想和若干试验结果。分析了以抛光面为条件确定检偏器转角的方法,描述了利用可换物镜组方便地实现等倾干涉测量的方法,和为操作方便而设计的迅速形成干涉条纹装置及双菱形镜对准装置等问题。 Utilizing the advantages of laser, a kind of polarization laser multi-purpose interferometer with convenient operation, wide range of uses and high precision is developed. The instrument uses a quarter-wave plate, polarization beam splitter system that can adjust interference fringe contrast and eliminate the effects of residual reflections on the optical system’s surfaces. Mainly introduced the design of the instrument and a number of test results. The method of determining the angle of the analyzer by the condition of the polished surface is analyzed. The method of using the interchangeable objective lens to realize the measurement of the equal inclination interferometer and the method of rapidly forming the interference fringe device and the double rhombic mirror designed for the convenience of operation are described Device and other issues.
