The fiber and the Bragg grating technology can be controlled pretty well today and represent no problem any more. The main problem comes from the requirement to induce the strain precisely into the fiber.
A novel measuring method to monitor excessive wear on the frog, as part of S&C, based on fiber Bragg grating (FBG) optical fiber sensors, is discussed in this paper.
In this report, we demonstrate a new scheme based on an FBG sensor fabricated in a polarization-maintaining fiber.
Because FBG sensors can measure strain (and not displacement) they also provide the superior advantages of the strain measuring principle, as metal foil strain gages do.
The work is devoted to the consideration of methods for determining the strain of objects using fiber Bragg gratings under a high-frequency vibration or pulsed mechanical action, which is
