The paper introduces the basic principle of measuring displacement with laser interferometer, and gives a designing idea that realizes length measurement and angle measurement on one apparatus.
The main ideaof this lecture is put storing before the slip-rings to improve the centrifugal displacement non-contact measurement techniques.
本文以存储前移为主要思路,改进了离心场位移非接触测量技术。

This article put forward the idea that displacement is presented as composition displacement and image displacement as a kind of means of shape-designing.
