A novel approach of temperature monitoring using an optical fiber sensor based on time offset

Simultaneous monitoring of temperature, pressure, and strain through Brillouin sensors and a hybrid BOTDA/FBG for disasters detection systems

“…Table 5 shows the results of the three parameters monitoring (pressure, strain, and temperature). We choose to calculate pressure variation under fixed temperature changes, and also under strain variations, we employ the theory calculation and mathematical relation as expressed in (10) and (11). We deduce that temperature and pressure changes are more affected ones than the other, however, strain variation is rather influenced by wavelength variation in a hybrid BOTDA/FBG system.…”

“…Bao et al (2012) [5] adopted the use of synthetic aperture radar to check geographic information and to deduce about natural disaster decision [10]. Luo et al [4] and Zrelli et al [11] used OF sensors FBG and Brillouin scattering to monitor overhead transmission lines. Lu et al (2012) [12] applied virtual human resources (VHP) system virtual human resources to get ground information.…”
