Abstract

A device for calibrating a fiber-optic temperature measuring system has a broadband light source, a coupling-in device, which can couple light generated by the light source for calibration into an optical fiber of the temperature measuring system, a coupling-out device, which can couple components of the light source-generated light that are backscattered in the optical fiber out of the optical fiber. An evaluation device performs a calibration of the temperature measuring system on the basis of the backscattered components of the light.
