Computation of Hopkins’ 3-circle integrals using Zernike expansions [PDF]
The integrals occurring in optical diffraction theory under conditions of partial coherence have the form of an incomplete autocorrelation integral of the pupil function of the optical system.

Partially coherent ultrafast spectrography [PDF]
AbstractModern ultrafast metrology relies on the postulate that the pulse to be measured is fully coherent, that is, that it can be completely described by its spectrum and spectral phase. However, synthesizing fully coherent pulses is not always possible in practice, especially in the domain of emerging ultrashort X-ray sources where temporal ...

Diffractive shaping of excimer-laser beams for pulsed laser deposition [PDF]
We present a beam-shaping system for a pulsed laser deposition setup. This system is based on two diffractive beam-splitter gratings and is able to produce 2 × 2 mm2 flat-top distributions of UV light with a fluence of 3 J/cm2 on the target some 30 cm ...

Eigenvalue calibration methods for polarimetry [PDF]
Complex polarisation sensitive systems such as imaging Mueller matrix polarimeters are commonly calibrated using the eigenvalue calibration method. In this paper we present an extensive review of the method and an existing variant.

Mathematical model and dynamical analysis of the human equilibrium seeking training [PDF]
The purpose of this work is to determine the ability of the partial directed coherence method to identify the directed interaction between nonlinear systems correctly in presence of nonlinear couplings between systems, as well as in the case when the ...

A coherence theorem for pseudonatural transformations [PDF]
We prove coherence theorems for bicategories, pseudofunctors and pseudonatural transformations. These theorems boil down to proving the coherence of some free $(4,2)$-categories.

Partial Coherence Estimation via Spectral Matrix Shrinkage under Quadratic Loss [PDF]
Partial coherence is an important quantity derived from spectral or precision matrices and is used in seismology, meteorology, oceanography, neuroscience and elsewhere.

Partially coherent sources with radial coherence
Partially coherent sources with radial coherence are proposed. They present a circularly symmetric intensity profile and a degree of coherence whose absolute value only depends on the angular difference between the two considered points. In particular, the source is completely coherent at pairs of points belonging to the same radius.
