Application of OCT to examination of easel paintings [PDF]
, 2004 We present results of applying low coherence interferometry to gallery paintings. Infrared low coherence interferometry is capable of non-destructive examination of paintings in 3D, which shows not only the structure of the varnish layer but also the ...

Liquid crystal based spectral control for applications in optical communication and metrology
Results in Optics, 2020 The molecules of nematic liquid crystals (LCs), aligned in one average direction, constitute a birefringent medium. The molecules in nematic LCs of positive anisotropy (ne>no) get aligned in the direction of applied electric field due to the induced ...

Data analysis tools for persistent scatterer interferometry based on Sentinel-1 data
European Journal of Remote Sensing, 2019 This paper describes a Persistent Scatterer Interferometry procedure to process Sentinel-1 SAR data. Its most original part includes a set of tools to perform two key processing stages: a first 2 + 1D phase unwrapping, prior to atmospheric filtering, and

Ultrafast many-body interferometry of impurities coupled to a Fermi sea [PDF]
Science, 2016 Sluggish turmoil in the Fermi sea The nonequilibrium dynamics of many-body quantum systems are tricky to study experimentally or theoretically. As an experimental setting, dilute atomic gases offer an advantage over electrons in metals.

Superlubricious Surfaces Through Surface Attached Hydrogels Obtained by C,H‐insertion Crosslinking
Advanced Functional Materials, EarlyView.Taking synovial joints as a source of inspiration, the friction properties of surfaces covered with 1d‐swelling polyelectrolyte hydrogels in combination with a shear‐thinning aqueous lubricant are studied. Such systems obtained by C,H insertion crosslinking show superlubricious behavior, even surpassing the friction values reported for the natural ...
