摘要
从棱镜的结构特点出发,结合菲涅耳定律和等厚干涉原理,导出了格兰泰勒棱镜透射光强分布的有关公式,分析了在平面光波和会聚光束入射时,光强分布特征,并进行了实验测试,测试结果与理论结果相一致.理论和实验结果表明:平面光波入射时,产生等间距和等相衬度的条纹;发散光束入射时一般产生不平行的、宽度和相衬度连续变化的条纹.
Based on design feature of Glan-Taylor prism, and by using Snell＇s law and equal thickness interference,the distribution of transmitted light of an air-spaced polarizing prism with the incidence of collimated light beam and convergent wave were studied as a function of azimuth and incident angle. Experiments accordingly were conducted, and both theoretical and experimental results indicated that equal visibility and width of fringe were got with the incidence of collimated light;unequal visibility and width of fringe were got with the incidence of convergent light beam.
