Distributed acoustic sensor based on a two-mode fiber

Distributed acoustic sensor based on a two-mode fiber
A distributed acoustic sensor (DAS) based on two-mode fiber is demonstrated. By using φ-OTDR, the backscattered light from higher order mode can be used to quantify vibrations. By combining the result obtained from different mode, 2.52dB improvement in noise floor is achieved. The results confirm that few-mode fiber can be used for DAS applications.

Abstract

A distributed acoustic sensor (DAS) based on two-mode fiber is demonstrated. By using φ-OTDR, the backscattered light from higher order mode can be used to quantify vibrations. By combining the result obtained from different mode, 2.52dB improvement in noise floor is achieved. The results confirm that few-mode fiber can be used for DAS applications.
