ABSTRACT

Computerized tomography has been used as a diagnostic technique for studying inhomogeneous turbulent density fields from optical path length data obtained at different viewing angles. The contribution of each element of the turbulent field to the path integral depends on the local turbulent intensity and the distance of the element from the detector. An iterative algebraic reconstruction algorithm, based on full discretization, has been used to solve the distant-dependent Radon transform. The algorithm has been studied by applying it to turbulent optical path length data obtained by computer simulations of two phantoms. The results show accurate reconstructions. The effects of ray ordering and relaxation parameters on reconstruction accuracy has been studied. More... »
