biprism interference

基本解释

Experimental results of electron interference and Fresnel diffraction observed on a transmission electron microscope using an electrostatic biprism as beam-splliter are reported.
本文报道了在透射型电子显微镜中，以静电双棱镜作分束器，观察到电子束干涉和菲涅耳衍射的实验结果。
The wavelengths are determined usually by measuring the widths of interference fringes in many experiments such as Young's slits, Fresnel biprism, bimirror and Lloyd's mirror etc.
杨氏双缝、菲涅耳双棱镜、双面镜以及劳埃镜等实验测定光波波长时，均是用测量干涉条纹宽度法。
This article aims at the shortcomings which in the biprism interference experiment teaching to make the teaching improvement: Introduces the camera to strengthen teaching intuitive;
本文针对双棱镜干涉实验教学中出现的弊端进行教学改进：引入摄像头增强教学直观性；
