MS 01 FBG FIBER OPTIC BRAGG GRATING STRAIN GAUGE

Fiber Bragg Grating Strain Desensitization

Fiber Bragg Grating Strain Desensitization

To address the issue of extra-large structural deformation or strain in infrastructures such as bridges, buildings, railroads, and pipelines during catastrophic events, this study proposes a wide-range fiber Bragg grating (FBG) strain sensor utilizing a snake spring. This research focuses on a desensitization method to develop a wide-range FBG sensor for extra-large strain monitoring, which is an essential requirement in large scale infrastructures or for some special occasions. Under appropriate hypotheses, the strain transfer distribution of wide-range FBG. Fiber Bragg grating (FBG) sensors, a relatively new fiber-optic technique where struc-tural strain influences the peak wavelength of the reflected wave from in the FBG, consti-tutes an inscribed Bragg grating and encapsulated protective packaging.
