This paper contains the theory behind optical fiber sensing measurement and the latest trends in optical fiber sensing measurement and its applications. Smart structures and materials in which an optical fiber acts as a sensor to measure distributed strain and/or temperature along the fiber have applications in health monitoring functions, such as preventive maintenance, product efficiency improvement,...
We have developed a prototype Brillouin optical time-domain reflectometry (BOTDR) system, called a double-pulse BOTDR (DP-BOTDR) system, for measuring distributed strain and temperature along fiber with a sub-meter spatial resolution. Oscillatory and steep power spectra of Brillouin backscattered signal have been observed with the DP-BOTDR, which allows us to measure Brillouin frequency shift accurately...
A novel Brillouin optical time-domain reflectometry (BOTDR) system, called a double-pulse BOTDR (DP-BOTDR) system, is proposed for measuring distributed strain and temperature in a fiber with a sub-meter spatial resolution. The DP-BOTDR system transmits double-pulsed lights instead of conventional single-pulsed lights into the fiber, and the received Brillouin backscattered signals are passed through...
