摘要
从射线方程出发，在光学几何近似的条件下，推导出角增量法射线追踪以及快速和精确的射线追踪算法。对于透射地震层析成像中网格单元坐标。
Starting from the ray equation and on the basic of the approximation similarity of optical geometry, the author deduces the method of angle increment ray tracing and a quicker and more precise numerical method, which contributes a lot to the grid unite coordinate, length of ray and the calculation of travel time in seismic approximation CT.
