摘　　要：基于几何光学原理得到一般三棱镜光垂直入射点M与底边和B角的关系式,研究一般三棱镜所需观察测量的出射光线与入射点、底角B、折射率等的关系。应用Matlab得到了母线段BM与底角B、棱镜折射率及两侧折射率的关系曲线,应用Zemax得到了相应的光线轨迹图。结果表明,理论分析与关系曲线和光线轨迹是一致的,对三棱镜应用中选择折射率、入射光线入射角、入射点和底角等有很好的参考作用,同时加深了对三棱镜折射理论和应用的理解。Based on the principle of geometric optics,the relationship between the normal incident point M of light of general prism and the bottom edge and Bangle is obtained,and the relationship between the outgoing light required to observe and measure the general prism and the incident point,bottom angle B,refractive index,etc.is studied.Matlab is used to obtain the relationship curve between the parent line BM and the bottom angle B,the refractive index of the prism and the refractive index of both sides,and Zemax is used to obtain the corresponding ray trajectory.The results show that the theoretical analysis is consistent with the relationship curve and ray path,which is a good reference for the selection of refractive index,incident angle,incident point and bottom angle of incident light in the application of triangular prism,and also deepens the understanding of the refraction theory and application of triangular prism.
