Abstract

A phase-sensitive optical time domain reflectometry sensing system based on Ultra-weak FBG Array using double pulses is proposed. The principle of this sensing system is elaborated. A series of simulations are carried out to optimize the parameters to increase the sensing distance of this system. The parameters contain reflectivity of UWFBG the interval between adjacent UWFBGs and pulse width. The optimal reflectivity and pulse width corresponding to different grating space are found out to achieve a longer sensing distance.
