Optical phase-spaces represent fields in terms of spatial and spatial frequency variables. Typically, phase-spaces are measured through phase-retrieval methods involving a computational inversion, or a lenslet array, which sacrifices resolution in one domain for the other. Recently, a quantum weak-values technique demonstrated that a beam's Dirac phase-space is proportional to the measurable complex weak-value, regardless of quantum state purity. These direct measurements require scanning… Expand
