Abstract EN
We present a simplified configuration for distributed Brillouin optical time-domain analysis sensors that aims to reduce the cost of the sensor by reducing the number of components required for the generation of the two optical waves involved in the sensing process.
The technique is based on obtaining the pump and probe waves by passive optical filtering of the spectral components generated in a single optical source that is driven by a pulsed RF signal.
The optical source is a compact laser with integrated electroabsorption modulator and the optical filters are based on fiber Bragg gratings.
Proof-of-concept experiments demonstrate 1 m spatial resolution over a 20 km sensing fiber with a 0.9 MHz precision in the measurement of the Brillouin frequency shift, a performance similar to that of much more complex setups.
Furthermore, we discuss the factors limiting the sensor performance, which are basically related to residual spectral components in the filtering process.
