Sažetak
A distributed temperature sensing systems is implemented and described. The system is based on optical time-domain reflectometry, and Raman non-linear scattering effect. The basic theory of optical fibres and their application in communication systems is described, along with significant linear and non-linear fibre-optical effects. Two reflectometric methods for characterizing optical fibres are explained. The implemented system is thoroughly described, calibrated and tested. Results obtained using two different laboratory setups, based on single-mode and multi-mode fibres, are presented. Sensor system performance is discussed, and methods for future enhancements are suggested.
