Here, we reinterpret the operation of wavefront sensors as a simultaneous unsharp measurement of position and momentum. Utilizing quantum tomography techniques we report an experimental characterization and 3D imaging of a multimode laser light.engjournal articlehttp://dx.doi.org/10.1117/12.2188040http://proceedings.spiedigitallibrary.org/open access535Wavefront sensingCoherenceTomographyParameter estimation3D imagingÓptica (Física)2209.19 Óptica Física
