一、前言散射板干涉仪是一种共光路形式的干涉仪,它具有结构简单、抗干扰能力强、对辅助光学系统要求较低、干涉条纹判读方便等优点。自1953年问世以来,在理论和实验上都得到了较快的发展,但迄今为止,在散射板制作和仪器调整方面仍存在着一定的困难,本文即针对这一问题设计了新的散射板制作光路,并介绍一种简单、精确的散射板干涉仪调节方法。二、散射板的制作方法图1为散射板干涉仪的原理图。投影物
I. Introduction The diffuser interferometer is a type of interferometer with a common optical path. It has the advantages of simple structure, strong anti-interference ability, low requirement for auxiliary optical system and convenient interpretation of interference fringes. Since the advent of 1953, both the theoretical and experimental development have been rapid development, but so far in the production of diffuser and instrument adjustment there are still some difficulties, this paper is to address the issue of designing a new diffuser Make the optical path, and introduce a simple, accurate method of adjustment of the diffuser interferometer. Second, the production of the diffuser plate Figure 1 Schematic diagram of the diffuser interferometer. Projection
