Viscous Relaxation

A regenerated fiber Bragg grating (RFBG) in silica fiber was used to observe the viscous relaxation process of the host silica fiber at high temperatures of around 1000 °C. Two factors, preannealing time and loaded tension, which affect viscous relaxation, were observed. When an RFBG is stretched after a longer preannealing, the measured viscosity of the optical fiber was observed to reach equilibrium faster, which means that preannealing accelerates viscous relaxation. A similar acceleration phenomenon was also observed when a larger load was applied to stretch the optical fiber, although the acceleration effect of loaded tension was not as strong as in the preannealing case. The results play an active role in establishing effective optical-fiber devices for application in high-temperature environments.

Abstract: Optical Fiber Sensor (OFS) has come quite considerable and famous in world of sensor technology where it has been used widely to detect for a changeable environment and responds to some output on other system such as in industrial, chemical analysis and monitoring. A Fiber Bragg Grating (Fiber Bragg Grating) is a kind of appropriated where the short fragment of optical fiber which certain and specific wavelength is reflected with light and the Bragg reflector started developed and transmits all others. The current project is concerned with the development characteristics and behaviors of strain and temperature sensors acting on Fiber Bragg Grating by a computer simulation. This study focuses on analyzing the performance of the characteristics and behavior of strain and temperature sensors acting on Fiber Bragg Grating. A strain sensor is used to measure strain on an object of which the resistance varies range with applied force. Meanwhile,for the temperature sensor is used to measure and detect any abnormality of temperature acting on Fiber Bragg Grating such as can lead into fire and accidents. This will found out on how Fiber Bragg Grating can demonstrate strain and temperature sensors. A simulation of the computer program (MATLAB) will be carried out to simulate due to the strain and temperature sensor of Fiber Bragg Grating.

Index Modulation

In this work, uniform Fiber Bragg Grating (FBG) temperature sensor system were implemented and investigated due to measurement of the Bragg wavelength shift. An (FBG) is an optical fiber in which the refractive index in the core is perturbed by Germanium, forming a periodic index modulation profile. When light is guided through a fiber granting, it is scattered at each diffraction plane, except at those wavelengths which satisfy the Bragg resonance conditionAn important application of FBG technology is sensing. The reflected wavelength from the FBG depends on physical properties such as temperature. By integration the FBG with broadband light, the shift in peak reflectivity wavelength can be used as a measure for the temperature.It has been shown from the results that the FBG is very sensitive to variations in temperature degrees and the sensitivity was (1pm/0.1°C), also observed from the results, the relation between the shifted Bragg wavelength and temperature degrees was linear.
