  • Fatigue of Fiber Bragg Grating Sensors

    Fatigue of Fiber Bragg Grating Sensors

    This paper investigates the fatigue performance of Type I and Type II through-coating FBG sensors with different fibre geometries and photosensitisation approaches to evaluate their overall reliability and durability, with a view to assess their performance for potential use in. This paper investigates the fatigue performance of Type I and Type II through-coating FBG sensors with different fibre geometries and photosensitisation approaches to evaluate their overall reliability and durability, with a view to assess their performance for potential use in. Although fibre Bragg gratings (FBGs) offer obvious potential for use in high-density, high-strain sensing applications, the adoption of this technology in the historically conservative aerospace industry has been slow. There are several contributing factors, one of which is variability in the. Strain sensing technology using fibre Bragg grating (FBG) sensors is an attractive capability for aerospace structural health monitoring (SHM) and assessment because they offer resistance to harsh environments, low maintenance, and potential for high density and high strain sensing.

  • Principle of Fiber Bragg Grating Liquid Level Sensor

    Principle of Fiber Bragg Grating Liquid Level Sensor

    In this paper, we present a fiber sensor using a fiber Bragg grating encapsulated in a half-polymer-filled metal cylinder for measuring liquid level variation. The operating mechanism of this novel design is based on transferring radial pressure into axial strain to induce Bragg wavelength shift. Referencing to a same liquid level (of a liquid reservoir or reference sensor), a group of such sensor interrogated simultaneously by a FBG interrogator can construct a differential. Fiber Bragg grating has embraced the area of fiber optics since the early days of its discovery, and most fiber optic sensor systems today make use of fiber Bragg grating technology.
