The challenge of phase recovery from the experimentally available magnitude of the signal
appears in various fields of science and engineering. To prepare a broad framework and …

Context. The sparse layouts of radio interferometers result in an incomplete sampling of the
sky in Fourier space which leads to artifacts in the reconstructed images. Cleaning these …

The van Cittert–Zernike theorem is extended to the vectorial regime based on spatial
averaging over the observation plane, and experimental demonstrations are presented. The …

The concept of ensemble-average polarization and coherence has been applied to studying
fluctuating Stokes parameters in a polarization speckle observed when coherent light is …

We formulate the van Cittert–Zernike theorem for spatially incoherent partially polarized
sources in terms of the traditional polarization (one-point) Stokes parameters and the …

Extension of coherence holography to vectorial regime is investigated. A technique for
controlling and synthesizing optical fields with desired elements of coherence-polarization …

We explore applications of quantum computing for radio interferometry and astronomy using
recent developments in quantum image processing. We evaluate the suitability of different …

The two-point counterparts of the traditional Stokes parameters, which are called the
coherence Stokes parameters, have recently been extensively used for assessing the …

Radio frequency interference (RFI) presents a large problem for radio telescopes.
Interference prevents observations from being made, or extends the duration required for …

We address polarization coherence in terms of correlations of Stokes variables. We develop
an scalar polarization mutual coherence function that allows us to define a polarization …
