摘　　要：基于几何光学原理分析研究一般三棱镜的入射点D,得到入射点D与距离BD、折射率、入射角、棱镜角之间的关系,应用Matlab得到对应的关系曲线,应用Visio得到光线传播轨迹.研究得到要观察到实验所需的出射光线时,入射点D、折射率、入射角、棱镜角都要满足一定要求,为实验选择棱镜及实验环境提供理论参考,拓展丰富教学和实验内容.Based on the principle of geometric optics,analyze and study the incident points D of general triangular prism,get the relationship between the incident point D and distance BD,refractive index,incident angle,prism angle apply Matlab to obtain the corresponding relationship curve,and Visio to obtain the ray propagation path.The research shows that the incident point D,refractive index,incident angle and prism angle must meet certain requirements to observe the outgoing light required by the experiment,which provides theoretical reference for the selection of prism and experimental environment in the experiment,and expands and enriches the teaching and experimental content.
