Long Range Raman-Amplified Distributed Acoustic Sensor Based on Spontaneous Brillouin Scattering for Large Strain Sensing
A Brillouin distributed acoustic sensor (DAS) based on optical time-domain refractometry exhibiting a maximum detectible strain of 8.7 m [Formula: see text] and a low signal fading is developed. Strain waves with frequencies of up to 120 Hz are measured with an accuracy of 12 [Formula: see text] at...
