Project description:Optical fibers and namely the special optical fibers (PMD-Polarization Maintaining Fibers, PCF-Photonic Crystal Fibers) have important applications as Sensors with Distributed Parameters (SDP). By use of SDP one can pick up space change distributions of all physical quantities that are capable to influence in some way the refraction index inside the fiber core. These changes can be detected by use of Optical Time-Domain Reflectometry (OTDR) and its various modifications that are still under development. OTDR makes possible to measure the back scattered optical power as a response to a rather short and powerful optical test impulse. In principle in such a way one can pick up the space distribution of temperature, mechanical tension, pressure or friction along the body as e. g. steam turbine, bridge construction, building structures, along the airplane wings and so on. During the recent time a lot of effort is given to the development of fiber optic sensors with distributed parameters.
