摘要：不同于传统全息光栅制作教学实验中的分振幅干涉光路,提出了利用准平行相干光源照射菲涅耳双棱镜实现分波前干涉制作全息光栅的方法.利用菲涅耳双棱镜分波前光路分别演示了单个双棱镜制作一维全息光栅和2个棱脊正交菲涅耳双棱镜制作二维全息光栅.实验过程中可通过多种方法对干涉条纹间距和光栅常量进行估算,丰富了干涉实验内容和光栅制作实验内容.
Different from the interference light path in traditional holographic grating making experiment,a new method of fabricating holographic gratings by using quasi parallel coherent light source to irradiate Fresnel double prism to realize wavefront splitting interference was proposed.The fabrications of one-dimensional holographic grating with a single Fresnel prism and two-dimensional holographic grating by two Fresnel prisms with orthogonal ridges were demonstrated.The interference fringe distance and the grating constant were estimated by many methods.The experimental contents of light interference and grating fabrication were enriched.
