摘 要: 应用基尔霍夫—菲涅耳衍射理论,分析了菲涅耳双棱镜对柱面波的相位调制作用,得到双"虚光源"距离和条纹间距等与几何光学一致的结果. By application of the Kirchhoff-Fresnel diffraction theory,the phase modulation effect of Fresnel biprism upon cylinder wave is analysed,and results consistent with the geometrical optics concerning the distance between two virtual light sources and stripe spacing are obtained.
