在地震学中一个非常重要的问题是研究地震波通过三维介质模型的传播。如果模型为多层弯曲界面构成,则透射波唯一的可行解需根据几何光学近似求得。透射射线,透射波场,以及与透射点有关的第一菲涅耳带可由4个2×2常数矩阵表示,从而构成了4×4线性射线变换矩阵。射线变换矩阵通常由动态射线追踪构成,可是,如果地层为均匀层,则经过基本矢量
A very important issue in seismology is to study the propagation of seismic waves through three-dimensional media models. If the model is composed of a multi-layer curved interface, the unique feasible solution of the transmitted wave needs to be obtained from the geometrical optics approximation. The transmitted ray, the transmitted wavefield, and the first Fresnel zone related to the transmission point can be represented by 4 2 × 2 constant matrices, forming a 4 × 4 linear ray transformation matrix. Ray transformation matrix is usually composed of dynamic ray tracing, but if the formation is a uniform layer, then the basic vector
