Distributed Temperature Sensing (DTS)
Optical Time-Domain Reflectometry (OTDR) –
Raman Effect
- Fiber optic sensor cables.
- Location corresponding to a measured backscattered light signal.
- Ratio of the Stokes and anti-Stokes signals determines the temperature.
- Short optical laser pulse results in high spatial resolution.
- One wavelength (1064 or 1550nm) or two wavelengths systems (to overcome “hydrogen darkening”).
