    "abstract": "We show that the resolution \"per absorbed particle\" of standard absorption\ntomography can be outperformed by a simple interferometric setup, provided that\nthe different levels of \"gray\" in the sample are not uniformly distributed. The\ntechnique hinges upon the quantum Zeno effect and has been tested in numerical\nsimulations. The scheme we propose could be implemented in experiments with\nUV-light, neutrons or X-rays.",
