Abstract
⺠In HAADF STEM, a thickness dependent, non-linear damping of the projected intensities occurs. ⺠In tomography, this leads to underestimated intensities in the interior of homogeneous particles, the cupping artifact. ⺠The non-linear damping is demonstrated in experimental images and reproduced with numerical simulations. ⺠The non-linear damping can be undone if the imaging is done quantitatively. ⺠Experimental proof is provided showing that cupping can be prevented.
