Abstract: The paper considers the inverse problem of determining the refractive index of optical media using four-angle Hilbert visualization of phase disturbances. The phase functions for each projection (Radon data) are reconstructed using the Gauss-Newton iterative algorithm. The refractive index is determined using the Gerchberg–Papoulis algorithm based on a discrete analog of the central slice theorem for the four-angle case. The results of numerical modeling are presented.
