Abstract

Raman-based Distributed Temperature Sensing (DTS) utilizing fiber probes is an effective method to determine temperature over distances up to 20km. Active Plug & Play is based on a full DTS solution (DTS system with PerfectVision^TM, Calibration Module, SensorTran DTS Commander software) using a dual laser approach with light sources operating at different wavelengths to determine and compensate for the wavelength dependent local variations in fiber attenuation. The wavelength values for the anti-Stokes Raman return of the primary light source is approximately the same value as the Stokes Raman return of the secondary source. This solution enables the first auto-correcting calibration for DTS.
