Analysis of images caused by vertex angle of a prism and their application;

In this paper, the relationship between the emergent light ray angle and incidence point is investigated according to the principle of the geometric optics and the computer simulation experiment so as to obtain the dependence of the incidence point on the vertex angle of the prism, refraction index and the basal-plane length of the prism from MATLAB.

This article emphatically discussed the influence of different vertex angle as well as the different refractive index to the minimum deviation angle of triangular prism, thus we had a certain understanding to the prism deviation rule.
