Abstract: The research of ultra-multi-point strain detection is one of the important topics at the
forefront of optical fiber sensing technology. A newly ultra-multi-point strain measurement
system was designed based on optical time-domain reflectometry (OTDR) and Fiber Bragg
Grating. Two distributed feedback (DFB) lasers is proposed as laser source to generate the
alternately pulsed light, and transmitted to a serial of fiber Bragg gratings with the same
low-reflectivity and bandwidth. By the means of the strength of each reflectance spectrum and
its return time of signals, the magnitude and location of strain can be accurately determined, and
