Preliminary results on approximating the signatures for ROIs probed in the synthetic aluminium single crystal for different strengths of positional noise. The colour bars display the image intensity using individually linear scales with values that range from 0.0 to the shown individual maximum intensities. Spherical harmonics approximated spherical images (of the signatures in the left-hand column). We compared the approximations for 64 and 512 spherical harmonics modes.
