  • Repeatability of Fiber Optic Sensors

    Repeatability of Fiber Optic Sensors

    These sensors use light signals to detect physical parameters such as temperature, pressure, strain, and vibration. The performance of fiber optic sensors can be evaluated based on several key factors including sensitivity, accuracy, resolution, linearity, hysteresis. Our findings highlight that elongating sensing length detrimentally affects both linearity response and repeatability, largely attributed to a diminished resistance to noise. Additionally, the choice of the optical source wavelength proved to be a critical variable in assessing sensor sensitivity. In this paper, accuracy calibration experiments and the related analyses of two fiber-optic sensing technologies, the fiber-optic grating (FBG) and optical frequency domain reflectometry (OFDR), are carried out using a standard beam of equal strength and a mature resistive strain gauge (ESG). The performance of. Although the IEEE-SA Industry Connections activity members who have created this Work believe that the information and guidance given in this Work serve as an enhancement to users, all persons must rely upon their own skill and judgment when making use of it. IN NO EVENT SHALL IEEE OR IEEE-SA.
