The red & blue traces represent the Stokes and anti-stokes signals respectively.
Some key features to note about the raw signal traces are:
•
The section from -50 to 0m is the internal reference oven of the DTS
•
The zero meter point is at the DTS output connector
•
With good, continuous fibre, the traces will show an exponential decay.
Point losses and temperature events along the fibre will cause the traces
to deviate from a smooth exponential profile
•
The end of the fibre will be visible if less than the maximum range
•
The background, no light, level should be at zero on the Y-axis
