Opis:: Distributed temperature sensing systems (DTS) has improved over years thanks to the improvements in configurations, components and demodulation calculating algorithms. The demodulation algorithms have been improved depending on the application and the environment, in which the fiber is installed, in order to obtain accurate measurements of temperature and distance. This study discusses the conventional calculating methods and proposed algorithms for different configurations for DTS systems.

Opis:: A laboratory system for measuring the Raman scattering light in optical fiber is presented. The system is equipped with the developed driver for 5 mW/1550 nm laser diode, optical circulator, WDM filters to separate Rayleigh and Raman scattered light and InGaAs cooled photodiode to detect the weak scattered radiation. Instead of using expensive network analyzer we propose to use Software-Defined Radio, which ensures the necessary sensitivity and selectivity of detected signals. The preliminary results are presented for about 3 km – length single mode silica optical fiber.

Opis:: Distributed temperature sensing (DTS) based on Raman scattering in optical fibers gains more importance in several applications, due to its accuracy, immunity to electromagnetic interference and corrosion, durability, low cost and availability. DTS systems are configured differently depending on the environment of application, and uses Optical Time Domain Reflectometry (OTDR) or Optical Frequency Domain Reflectometry (OFDR) for data analyzes. This study features a theoretical background and an introduction to DTS systems’ configurations and applications.
