“…Finally, we might wonder whether there is any more information to be retrieved from the ray transforms Iw and Iu, or alternatively Ï and Í, as so far we could only reconstruct one tensor component from these data. The answer is no: As proven in [13], if any two stress tensors σ (1) and σ (2) satisfy (26, 27) and σ (1) 33 = σ (2) 33 then they produce the same ray transforms, Iw (1) = Iw (2) and Iu (1) = Iu (2) . As a consequence, the retrieval of one tensor component is the maximum information to be gleaned from a ray transform which is performed for horizontal lines only.…”

“…A transparent optical medium which initially is isotropic and homogeneous with respect to light propagation may become birefringent when subjected to external strain, an effect which is known as Photoelasticity [1,2]. The spatially varying tensor of refraction then reflects the presence of stresses within the material, opening up the possibility of examining internal stresses by means of the change in the state of polarization of light beams passing through the strained medium.…”
