迈克尔逊干涉仪准直调节研究

Research on Collimation of Michelson's Interferometer

传统的迈克尔逊干涉仪存在调试困难,干涉花样模糊不清,分辨率偏低等缺点,因此有必要设计一种利用定制光阑进行迈克尔逊干涉仪准直调节的方法。光源通过光阑的通孔后,经分光板(镜)反射,在平面镜M1上形成红圈光斑,通过调节分光板、平面镜的螺丝,不仅可以在较短的时间内将整个光路准直完毕,而且还能保证干涉花样的中心正好位于光屏的正中,便于后期观测。利用该准直方法的干涉花样进行激光波长测试,误差仅为0.01%,表明该方法切实有效。

A custom diaphragm is applied in the collimation of Michelson interferometer.Through the light spot position reflected on the planar reflector,we can easily adjust the screws of spectroscope and the mirrors,which not only decreases the time of collimating heavily,but also ensures that the center of the interference pattern is in the midst of the screen,which contributes to the later observation and measurement.
