双参考镜合像干涉仪的研究

Study of interferometer of double reference mirrors

介绍一种新型干涉测量系统，该系统采用并列的两个参考镜，将产生的两组干涉条纹复合在同一视场。当测量系统产生的光程改变时，两组干涉条纹相对关系按一定规律变化，借助光电转换和图像分析技术，可用于长度和微小角度测量。介绍了可行性实验和测取的数据及分析所得出的结论。

Introduces a new type of interferometric measuring system.Using the two reference mirrors abreast, this system combines two sets of interferometric fringes changed baser on certain rules due to the photoelectric convertion and graphical analysis technology , It Can be used in length and micro - angle measurement. Introduces the feasible experiments, the measured data and the conclusion from analysis.
