Distributed X Sensing (DXS)

DTS – Temperature

DAS – Acoustic

DSS – Strain


  • Rayleigh (Acoustic):
  • Same wavelength as laser
  • Brillouin (Temperature/Strain)
  • ~11GHz shift
  • Frequency shift: Temperature
  • Amplitude deviation: Strain
  • Raman (Temperature)
  • ~13THz shift
  • Stokes/Anti-Stokes relation:
