Technical Note
DITEST BOTDA
Omnisens DITEST exploits the sensitivity of the Brillouin frequency shift for temperature and strain sensing applications.
Brillouin frequency-based technique is opposed to intensity based techniques such as Raman and is inherently more accurate and more stable in the long term, since intensity-based techniques suffer from a high sensitivity to drifts.
Brillouin scattering can be optically stimulated leading to the greatest intensity of the scattering mechanism and consequently an improved signal-to-noise ratio. The technique uses standard low-loss single-mode optical fibre offering more than 40 kilometres of distance range with the highest performance and a full compatibility with standard telecommunication components.
