tomography

Abstract: Optical deflection tomography based on phase-shifting Schlieren is well adapted for three-dimensional imaging of objects with large refractive index variations. We propose a reconstruction algorithm that takes into account light refraction and spatial sparsity of the sample.

I have just found this “new” (well 150 years old actually) tomographical method… for measuring the magnetic field of our own galaxy “New all-sky map shows the magnetic fields of the Milky Way with the highest precision”
