Spatial statistics of superposition of two uncorrelated speckle patterns with polarization diversity
A detailed theoretical and experimental study on the effect of the superposition of uncorrelated speckle patterns with polarization diversity on the spatial statistics of the superposed speckle pattern is presented. It is shown that depending on the mutual ...
Elsevier20213D reconstruction of weakly scattering objects from 2D intensity-only measurements using the Wolf transform
Demetri Psaltis, Joowon Lim, Elizabeth Elena Antoine, Ahmed Ayoub
A new approach to optical diffraction tomography (ODT) based on intensity measurements is presented. By applying the Wolf transform directly to intensity measurements, we observed unexpected behavior in the 3D reconstruction of the sample. Such a reconstru ...
OPTICAL SOC AMER2021Improvement of Mott spin polarimeters: An overlooked redundancy
In Mott polarimeters, the measurement of the spin polarization of an electron beam along two perpendicular quantization axes is commonly performed by collecting scattered electrons with four independent detectors placed azimuthally at 90 degrees from each ...

Demetri Psaltis, Christophe Moser, Navid Borhani, Damien Claude-Marie Loterie, Eirini Kakkava, Babak Rahmani, Ugur Tegin
The output of physical systems, such as the scrambled pattern formed by shining the spot of a laser pointer through fog, is often easily accessible by direct measurements. However, selection of the input of such a system to obtain a desired output is diffi ...
SPRINGERNATURE2020Brillouin scattering in gas-filled hollow-core fibres
Edward E. Hagenlocker and William G. Rado demonstrated Brillouin interaction in gas for the first time in 1965, right after the very first demonstrations of stimulated Brillouin scattering in solid materials. In their experiment, they used a megawatt pulse ...
EPFL2020Inverse Analysis of Radiative Flux Maps for the Characterization of High Flux Sources
Sophia Haussener, Clemens Gregor Suter, Gaël Jean Clément Levêque
The reconstruction of the angular and spatial intensity distribution from radiative flux maps measured in high flux solar simulators or optical concentrators is an ill-posed inverse problem requiring special solution strategies. We aimed at providing a sol ...
