Imaging polarimetry for the determination of stress constraint in transparent solids
EPJ Web of Conferences, 2010 Using a Mueller matrix polarimeter based on liquid crystal cells [1] and the forward polar decomposition [2], we study the evolution of the birefringence property induced by an increasing compression of a Plexiglas sample.

Apparatus for time‐resolved measurements of acoustic birefringence in particle dispersions [PDF]
, 1995 An apparatus for time‐resolved measurements of the birefringence induced in a particle suspension by an acoustic wave pulse is described. Efficient acoustic coupling is obtained by operating near the transducer resonant frequency and by matching the ...

Long-Time Relaxation of Stress-Induced Birefringence of Microcrystalline Alkali Halide Crystals
Molecules, 2018 Alkali halide single crystals are most commonly used as the diluent matrix in the tablet method or disk technique for spectroscopic measurements. However, stress-induced birefringence (SIB) of alkali halides as well as intrinsic birefringence manifest ...

Measurements of flow-induced birefringence in microfluidics [PDF]
Biomicrofluidics, 2016 In this study, we demonstrate the use of a microscopic circular polariscope to measure the flow-induced birefringence in a microfluidic device that represents the kinematics of fluid motion optically. Unlike the commercial birefringence microscope employed in the previous studies, our approach is able to provide direct measurement of retardance, which ...

Advanced Functional Materials, EarlyView.This study uncovers the unexplored role of intermolecular interactions in multiphoton absorption in coordination polymers. By analyzing [Zn2tpda(DMA)2(DMF)0.3], it shows how the electronic coupling of the chromophores and confinement in the MOF enhance two‐and three‐photon absorption.

Measurement of plasma current in Tokamaks using an optical fibre reflectometry technique
EPJ Web of Conferences, 2018 An optical time-domain reflectometer sensitive to the polarization of light is proposed for the measurement of plasma current in the Tore Supra fusion reactor. The measurement principle relies on the Faraday effect i.e.

Magnetic linear birefringence measurements using pulsed fields [PDF]
Physical Review A, 2012 In this paper we present the realization of further steps towards the measurement of the magnetic birefringence of the vacuum using pulsed fields. After describing our experiment, we report the calibration of our apparatus using nitrogen gas and we discuss the precision of our measurement giving a detailed error budget.
