DFOS Applications to Geo-Engineering Monitoring
Bin SHI, Dan ZHANG, Honghu ZHU, Chengcheng ZHANG, Kai GU, Hongwei SANG, Heming HAN, Mengya SUN, and Jie LI
Optical fiber sensing technology has developed rapidly since the 1980s with the development of the optical fiber and fiber optical communication technology. It is a new type of sensing technology that uses light as a carrier and optical fiber as a medium to sense and transmit external signals (measurands). Distributed

Review of Femtosecond-Laser-Inscribed Fiber Bragg Gratings: Fabrication Technologies and Sensing Applications
Jun HE, Baijie XU, Xizhen XU, Changrui LIAO, and Yiping WANG
Fiber Bragg grating (FBG) is the most widely used optical fiber sensor due to its compact size, high sensitivity, and easiness for multiplexing. Conventional FBGs fabricated by using an ultraviolet (UV) laser phase-mask method require the sensitization of the optical fiber and could not be used at high temperatures. Re
