On dynamic ray tracing in three dimensional inhomogeneous media

Abstract

Among the various dynamic ray tracing systems described by Cervený and Hron[1] is one particular linear system of second order that readily provides identical parameters (in the ray centred coordinate system) to those that fall out of the system by Popov and Psencik[3, 4]. Hence the initial conditions of the latter system for sources and interfaces can easily be used to provide those for the linear system of second order.
