    "abstract": "A method to reconstruct weakly anisotropic inhomogeneous dielectric tensors\ninside a transparent medium is proposed. The mathematical theory of Integral\nGeometry is cast into a workable framework which allows the full determination\nof dielectric tensor fields by scalar Radon inversions of the polarization\ntransformation data obtained from six planar tomographic scanning cycles.\nFurthermore, a careful derivation of the usual equations of integrated\nphotoelasticity in terms of heuristic length scales of the material\ninhomogeneity and anisotropy is provided, making the paper a self-contained\naccount about the reconstruction of arbitrary three-dimensional, weakly\nanisotropic dielectric tensor fields.",
