Abstract
A direct 3-D method is proposed in this paper for reconstructions of strongly refractive index fields. The basic idea is to reconstruct a refractive index field and to identify the ray path simultaneously. The 3-D ray tracing method and the curved ray algebraic inversion method based on many-knot interpolating spline technique and the solving method for linear equations by bidiagonalizing matrices are presented to realize the idea. The simulation experimental results are also provided.
