摘要：
Given a bounded domain M in R-n with a conformally Euclidean metric g = rho dx(2), we consider the inverse problem of recovering a semigeodesic neighborhood of a domain Gamma subset of partial derivative M and the conformal factor rho in the neighborhood from the travel time data (defined below) and the Cartesian coordinates of Gamma. We develop an explicit reconstruction procedure for this problem. The key ingredient is the relation between the reconstruction procedure and a Cauchy problem of the conformal Killing equation.
