17Distributed Acoustic Sensing Based on Optical Time‐Domain Reflectometry

17.1 Theory of Optical Time‐Domain Reflectometry

Acoustic array detection technology is indispensable for detecting the pressure waves in numerous applications, including ocean acoustic tomography [1], aviation noise analysis [2], oil well exploration monitoring [3], etc. The traditional acoustic arrays are mainly constructed by electrical microphones. The discrete structure of the electronic sensor and the stringent requirements of the synchronous acquisition make the scale of the microphone array extremely limited. Electromagnetic interference, high temperature, high humidity, and other adverse environments also raise a tremendous challenge for the reliable operation ...
