Interrogation of Optical Fiber Sensors for Civil Engineering Applications using Widely Tunable Laser
 Heininger, Hilmar ; Vlček, Čestmír (oponent) ; Roths, Johannes (oponent) ; Prokeš, Aleš (vedoucí práce)
This dissertation investigates the use of a MG-Y-Laser, a novel type of semiconductor laser that is electrically tunable over a wide spectral range, for the interrogation of Fiber Bragg Grating (FBG) based fiber-optical sensing networks. The research started with a complex long-term test of a real world measurement scenario from the field of civil engineering to elucidate limiting aspects of state of the art techniques. Civil engineering applications pose a multitude of mutually exclusive challenges toward structural sensing systems. These challenges are shared by many other fields of technology, making the results to a large degree universally applicable. Following an assessment of the state of art and the application requirements, the aspects to be improved by the research were identified. A Syntune/Finisar S7500 MG-Y-Laser device was then thoroughly characterized. Based on the gathered measurement data, novel tuning methods aimed at wavelength continuous control were investigated. This led to the invention of a tuning method that not only allows wavelength continuous control but also provides a means of self calibration based on intrinsic properties (longitudinal cavity modes) of the device.
