Experimental compressive phase space tomography

摘要: Phase space tomography estimates correlation functions entirely from snapshots in the evolution of wave function along a time or variable. In contrast, traditional interferometric methods require measurement multiple two–point correlations. However, as every tomographic formulation, undersampling poses severe limitation. Here we present first, to our knowledge, experimental demonstration compressive reconstruction classical optical function, i.e. mutual intensity function. Our algorithm makes explicit use physically justifiable assumption low–entropy source (or state.) Since was directly accessible experiment, were able compare estimate an independent ground–truth van Cittert–Zernike theorem and verify substantial quantitative improvements reconstruction.
