Applications of optical fibre sensors
Ráboňová, Jana ; Dejdar, Petr (referee) ; Münster, Petr (advisor)
This master's thesis deals with the measurement of soil temperature. In the theoretical part, optical fiber systems were explained, with a focus on DSTS systems and their use. In the practical part, a functional system was created to measure the soil temperature at depths of 0.1-1~m using the Arduino platform. Furthermore, the temperature measurement was demonstrated on the test polygon using the optical fiber of the FTB 2505 instrument in laboratories.

Optical Distributed Sensor Systems
Dorazin, David ; Münster, Petr (referee) ; Čučka, Milan (advisor)
This bachelors thesis solves possibilities of utilization optical fiber as a sensor. At the beginning the thesis desribes basic principle of ligh transmition in optical fiber, optical fiber and his linear and nonlinear properties. Second part of the thesis deals with sorting of distributed optical fiber sensors and describes each type of the sorted sensor due to principle which they work on. The Michelson interferometer is described and its modification in the form of the Fiber optic Michelson interferometer, which is designed and simulated in the VPIphotonics software. At the end of the thesis is performed measuring of vibrations by the Fiber optic Mach-Zehnder interferometer.

Distributed optical fiber sensors
Hynek, Jiří ; Šifta, Radim (referee) ; Münster, Petr (advisor)
Nowdays, optical fibers are one of important parts of computer networks, especially for their ability to transfer information for long distance. This thesis doesn´t utilize optical fibers as carriers, but as sources of information, specifically as sensors intended to detect physical effects acting on the optical fiber, which is usually used for telecommunication purposes. Linear and nonlinear properties of the fiber are used to gain information about acting effects on the optical fiber.

Data processing from fibre optic temperature sensors
Carboch, David ; Tomašov, Adrián (referee) ; Dejdar, Petr (advisor)
The bachelor thesis is dealing with fiber optic sensor systems, their division and properties. Furthermore, the thesis discusses the possibilities of fiber optic measurements in the nuclear power environment. Then the thesis contains possible methods of temperature measurement and their comparison. The thesis deals with the design of the sensing probe. Through the probe, the mechanical resistance of the sensing fiber and the handling of the sensing fiber have been improved. Furthermore, the thesis deals with the creation of an interactive chart of the relative temperature of a nuclear reactor in real time. In the chart, the dependence of reactor temperature change on reactor power and air temperature change can be observed. The measured results can be exported from the chart.
