Self-consistent phase determination for Wigner function reconstruction
We present the reconstruction of the Wigner function of a classical phasesensitive state, a pulsed coherent state, by measurements of the distributions of detected-photons of the state displaced by a coherent probe field. By using a hybrid photodetector operated above its photon-resolving regime, we obtained both the statistics at different values of the probe field and the values of the probe ...
متن کاملPhase Reconstruction from Two Wigner Distribution Projections
The connection between the instantaneous frequency and the angle derivative of the fractional power spectra is established. It permits to solve the signal retrieval problem if only two close fractional power spectra are known. This fact is used in the reconstruction of the Wigner distribution or the pseudo Wigner distribution from two close projections. Keywords—Wigner distribution, fractional ...
متن کاملDiscrete Wigner Function Reconstruction and Compressed Sensing
Wigner function(WF), a quasi-probability distribution in phase space, was first introduced to describe quantum state in quantum mechanics by E. P. Wigner[1]. And later, it was extended to classical optics and signal processing. Since its birth, a great number of applications have been conducted in different fields. As for the original quantum case, like a continuous onedimensional quantum syste...

متن کاملSelf-consistent Gravitational Lens Reconstruction
We present a new method for directly determining accurate, self-consistent cluster lens mass and shear maps in the strong lensing regime from the magnification bias of background galaxies. The method relies upon pixellisation of the surface mass density distribution which allows us to write down a simple, solvable set of equations. We also show how pixellisation can be applied to methods of mas...
