Abstract

A high precision distributed real time measurement for dynamic strain sensing in a chirped pulse phase optical time domain reflectometry (φ-OTDR) system based on random fiber grating array is experimentally demonstrated. The minimum detectable amplitude of dynamic strain is 52 nε with frequency of 1 Hz.
