    Two-point paraxial traveltime formula for inhomogeneous isotropic and anisotropic media: Tests of accuracy

  • Original language description

    On several simple models of isotropic and anisotropic media, we have studied the accuracy of the two-point paraxial travel-time formula designed for the approximate calculation of the traveltime between points S' and R' located in the vicinity of pointsS and R on a reference ray. The reference ray may be situated in a 3D inhomogeneous isotropic or anisotropic medium with or without smooth curved interfaces. The two-point paraxial traveltime formula has the form of the Taylor expansion of the two-pointtraveltime with respect to spatial Cartesian coordinates up to quadratic terms at points S and R on the reference ray. The constant term and the coefficients of the linear and quadratic terms are determined from quantities obtained from ray tracing and linear dynamic ray tracing along the reference ray. The use of linear dynamic ray tracing allows the evaluation of the quadratic terms in arbitrarily inhomogeneous media and, as shown by examples, it extends the region of accurate results
