Abstract
A temperature monitoring device containing a control system adapted to generate substantially periodic control waveforms applied to the control input of the light source with tunable wavelength connected to an optical fiber interferometer, in which a measuring optical fiber is connected in one its arms, and the interferometer output is connected to a detector whose output is connected to a signal processing module adapted to identify temperature changes in the optical fiber length function, in accordance with the invention, characterized in that the light source coherence length is longer than 0.5 m, and the period of the periodic waveform is shorter than or equal to 20 s, the difference between the minimum and maximum wavelength is higher than 3 pm, and the optical fiber is adapted to its placement near exoenergetic devices in a vehicle, during its operation. The temperature monitoring method according to the invention is characterized in that the temperature is determined by cumulatively accounting for changes detected using the device according to the invention at measurement points on the measuring optical fiber of this device. The temperature monitoring system according to the invention is characterized in that the measuring optical fiber of the device according to the invention is placed near exoenergetic devices in a vehicle.
