Abstract

Computer tomography can be used to reconstruct objects such as refractive index distributions in transparent media, if refraction is small enough that the probing optical rays are straight lines. Here we consider a ray-optical formulation of the corresponding problem, when refractive ray bending is significant. In the special case of axisymmetric objects the problem has an analytical solution, which is used in geophysical and atmospheric remote sensing. An iterative computational algorithm has been derived to effect reconstructions of strongly refracting objects and has been shown to work well in the case of relatively smooth distributions of refractive index.
