Broadband spectral shaping using nematic liquid crystal

open access: yesResults in Physics, 2019
We demonstrate what is, to our knowledge, the first implementation of nematic liquid crystal (LC) for spectral shaping of broadband light fields. A LC cell of several microns thickness is placed between a polarizer and an analyzer.

Application of OCT to examination of easel paintings [PDF]

open access: yes, 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 ...

Landau-Zener-Stuckelberg interferometry [PDF]

open access: yes, 2010
A transition between energy levels at an avoided crossing is known as a Landau-Zener transition. When a two-level system (TLS) is subject to periodic driving with sufficiently large amplitude, a sequence of transitions occurs.

Narrow linewidth single laser source system for onboard atom interferometry [PDF]

open access: yes, 2014
A compact and robust laser system for atom interferometry based on a frequency-doubled telecom laser is presented. Thanks to an original stabilization architecture on a saturated absorption setup, we obtain a frequency-agile laser system allowing fast ...

Sensitivity of a Bolometric Interferometer to the CMB power spectrum [PDF]

open access: yes, 2008
Context. The search for B-mode polarization fluctuations in the Cosmic Microwave Background is one of the main challenges of modern cosmology. The expected level of the B-mode signal is very low and therefore requires the development of highly sensitive ...
