Axisymmetric Flow-induced Birefringence Measurements for the Flow of a Polystyrene Boger Fluid into an Abrupt Contraction-expansion

We study the creeping flow of a dilute, monodisperse polystyrene/oligomeric styrene Boger fluid through axisymmetric abrupt contraction-expansions of various contraction ratios and over a wide range of Deborah numbers. Measurements of the entry pressure drop for the polystyrene solution increase monotonically with Deborah number and are substantially larger than those observed for a similar New...

Birefringence measurements on crystalline silicon

Crystalline silicon has been proposed as a new test mass material in third generation gravitational wave detectors such as the Einstein telescope (ET). Birefringence can reduce the interferometric contrast and can produce dynamical disturbances in interferometers. In this work we use the method of polarization-dependent resonance-frequency analysis of Fabry–Perot-cavities containing silicon as ...

Birefringence Measurements in Fibers Without Polarizer

A novel method is described which measures the delay between polarization eigenmodes in either highor low-birefringence fibers. The main advantage of this interferometric method is its ability to perform the measurements without the use of any polarizing device. This results in a particularly easy handling and makes this technique very suitable for systematic fiber controls. The obtained accura...
