    Question 1/3

    Why does DTS data typically require long traces, e.g. 10s of seconds to several minutes long, for a single temperature trace?

    1. A
      It takes that long to process the raw data to get a temperature value
    2. B
      The backscatter signal from the small amplitude Raman peaks returning to the detector is very low over a short interrogation period so the signal needs to be stacked over time to reduce increase signal above the noise floor.
    3. C
      The current hardware isn’t capable of taking shorter traces.
