  • 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?

    • It takes that long to process the raw data to get a temperature value
    • 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.
    • The current hardware isn’t capable of taking shorter traces.
