Abstract

FemtoFiberTec introduces the second generation of isotropic femtosecond point -by-point written FBGs with near zero polarization dependence in central wavelength and extremely low scattering loss . These features result in extremely precise static measurements required for accurate temperature monitoring and allow flexible sensor arrangement, also for large sensor assemblies and non-stationary installations.
