Abstract
We demonstrate a distributed fiber Raman sensor for absolute temperature measurement with spatial resolution on the order of 1 cm at 1550 nm wavelength in single mode fiber using superconducting nanowire single photon detectors. Rapid measurements are shown, with less than 60s integration period, allowing the demonstration of temperature evolution in an optical fiber recorded at over 100 resolvable, 1.2cm spaced, positions along the fiber simultaneously. This distributed sensor has potential application as a primary reference standard, in which high-accuracy, high-spatial-resolution temperature measurements can be obtained without the need for a separate temperature calibration standard.
