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”).
