Abstract During last decades, sensor elements based on the fiber Bragg grating (FBG) have been widely studied and developed due to advantages of immunity electromagnetic interference, compact size, high precision, so on. The FBG itself is sensitive axial strain temperature variation directly can indirectly measure these complex physical parameters, such as pressure, displacement, vibration, by using some specially designed elastic structures convert them into FBG. Whether fixed measured...
Purpose The purpose of this paper is to present the latest sensing structure designs and principles information detection fiber Bragg grating (FBG) displacement sensors. Research advance future work in field have been described, with background that deformation measurements are universal crucial for structural health monitoring. Design/methodology/approach This analyzes summarizes existing FBG technologies from two aspects principle (wavelength detection, spectral bandwidth light intensity...
The temperature compensation effect strongly influences the measurement accuracy of FBG sensors. most widely used methods can be classified into three types depending on encapsulation method: 1) dual-grating differential for fully pasted FBGs, 2) prestretched FBGs with both ends fixed, and 3) addition a temperature-reference FBG. In current reports, is performed based assumption that wavelength shifts two are same (or proportional to each other) synchronous variation. However, because...
This paper presents a fiber Bragg grating (FBG) displacement sensor with high abrasion resistance for monitoring of steel spring floating slab damping track. A wedge-shaped sliding block and an equal-strength beam form conversion mechanism to transfer the deflection beam, deflection-induced strain is exerted on two FBGs. special linear guide rail-slider precision rolling bearing have been adopted onto mechanism, which turned friction into thus significantly reduced during frequent...
The temperature compensation effect of FBG sensors is crucial to their measuring accuracy. In the design a sensor, two FBGs are often adopted subject positive and negative strains through packaging methods including all grating pasting two-end after pretension. Temperature sensor realized by using difference wavelength shift as sensing signal. current reports, performed based on assumption that shifts same. However, also influenced changing environment. This work presents an experimental...
