The possibility of processing small-view hilbertograms by the Gerchberg–Papoulis method to restore the spatial distribution of the refractive index was studied. The method consists in iterative transitions from the function estimates in the frequency and coordinate spaces with correction based on a priori information. Numerical modeling of the refractive index reconstruction for various test functions by the Gerchberg–Papoulis method using the Radon data, known for four angles, has been carried out. Using a four-angle tomographic complex implemented on the basis of a modified IAB-463M shadow device, experimental studies were carried out by the example of optical Hilbert diagnostics of reacting media in a high-speed shooting mode (up to 2000 frames per second).
