一、前言在干涉仪器中,用激光做光源极为广泛。激光器发出的光束是很细的,需用平行光管扩束才能满足使用要求。如何设计平行光管才能满足要求呢?我们就自己工作中遇到的一些实际问题谈几点看法。
I. INTRODUCTION In interferometry instruments, the use of a laser as a light source is extremely broad. The laser beam emitted is very thin, need to be expanded with a parallel tube to meet the requirements. How to design collimator to meet the requirements? We talk about some practical problems we encountered in our work.
