SECOND generation fs-Laser-written Fiber Bragg Gratings for High Accuracy Temperature Measurement in Harsh Environments

摘要

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.
