A comparison study of the sensing characteristics of FBG and TFBG
Abstract
Purpose
The purpose of this paper is to compare the sensing characteristics of uniform fiber Bragg grating (FBG) and tilted fiber Bragg grating (TFBG) by presenting a detailed research review. Temperature, axial strain, bending, vibration and refractive index measurands of FBG and TFBG sensor are presented and some significant differences are found.
Design/methodology/approach
Theoretical analysis and practical application in engineering are investigated and compared from other authors' research papers and self analysis. Spectra behavior of both FBG and TFBG are discussed.
Findings
There are found to be significant differences in temperature, axial strain, bending, vibration and refractive index sensing characteristics of FBG and TFBG.
Originality/value
The paper's analysis is comprehensive and clear and provides readers with the sensing characteristics of FBG and TFBG in detail.
