Optical low coherence reflectometry (OLCR) was used for the measurement of the local fiber Bragg grating (FBG) birefringence. The birefringence with resolution of 4 x 10(-6) was determined directly from oscillations in the OLCR amplitude with a spatial ...

Low birefringence measurement and temperature dependence in metre-long optical fibers
, 2015 We propose a relatively simple technique to infer the birefringence on single mode low-birefringence optical fibers based on the use of the Faraday effect.

The theoretical model of the Faraday rotation in the low birefringence optical fiber is proposed to serve as a convenient tool for the determination of the birefringence upper limit allowed to retain current sensor sensitivity.

POTDR techniques for measurement of fiber birefringence properties
, 2002 Polarization-sensitive optical time domain reflectometry techniques which are used for measurement of fiber birefringence properties are discussed. The techniques are based on the fact that evolution of backscattered field polarization is affected by ...

Measurement of birefringence of optical materials using a wedged plate interferometer
, 1990 A nondestructive technique for measuring the birefringence of optical materials such as calcite using wedged plate interferometer is presented. The sample needed for measuring the refractive index must be polished in the form of a parallel plate.

The Anatomical Record, EarlyView.Abstract Pterosaur dental biology remains poorly understood despite its importance for comprehending feeding strategies and flight adaptations. Here, we present the first comprehensive histological analysis of an ornithocheiriform pterosaur tooth from the Lower Cretaceous Crato Formation (Santana Group, Northeast Brazil).

Group-velocity-locked vector soliton molecules in fiber lasers
Scientific Reports, 2017 Physics phenomena of multi-soliton complexes have enriched the life of dissipative solitons in fiber lasers. By developing a birefringence-enhanced fiber laser, we report the first experimental observation of group-velocity-locked vector soliton (GVLVS ...

The Anatomical Record, EarlyView.Osteohistological sampling on different bones of theropod dinosaur documents discrepant age record, growth, and metabolism. This could result unprecise paleobiological inferences if samplings are based on single bones. However, multi‐bone sampling can attenuate these discrepancies, helping to infer growth dynamics and physiology of these extinct ...

, 2003 A Brillouin scattering technique has been applied to investigate the ultra-drawing process of polypropylene films. The gradual elastic changes during the drawing process showed the appearance of anisotropy and birefringence of the sample.
