Quantum tomography is an essential experimental tool for testing any quantum technology implementation. Transverse spatial quantum states of light play a key role in many experiments in the field of quantum information as well as in free-space optical communications. In this paper we propose and experimentally demonstrate the tomography of spatial quantum states with a deformable mirror. It may be used to significantly outperform the conventional method with a spatial light modulator in terms of speed and efficiency, at the same time providing polarization insensitive operation.
