In order to assess your understanding of the lesson materials, please select the most appropriate answer for each of the multiple choice questions below.
-
AIt takes that long to process the raw data to get a temperature value
-
BThe 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.
-
CThe current hardware isn’t capable of taking shorter traces.
