光阑尺寸对干涉条纹对比度的影响

Influence of Diaphragm size on Interference Fringe contrast

本文讨论用Ｈｅ－Ｎｅ激光器作光源时，光阑尺寸对干涉条纹可见度的影响。通过实验我们找到了最佳光阑的变化范围。

This paper discussed the influence of the diaphragm size on interference fringe contrastwith He-Ne laser,We descovered the best diaphragm size with the help of experiment.
