Demonstration kit for fiber optic sensing system
Beránek, Karel ; Klíčník, Ondřej (referee) ; Dejdar, Petr (advisor)
This bachelor thesis focuses on the design and implementation of a~demonstration kit for a~fiber optic sensing system. The thesis includes a~theoretical analysis of optical phenomena such as polarization, dispersion, and interference, which are crucial to understanding the principles of fiber optic sensors. The designed sensing system comprises a~Mach-Zehnder interferometer, a~UP-Board development kit, an external 24-bit sound card, and a~touch display. The practical part of the thesis is focused on the construction of the enclosure using 3D printing, the integration of individual components, the design of a~custom application, and the testing of the system. The results of this work contribute to the development of knowledge in the field of fiber optic sensors and can be utilized in both academic and industrial settings.

Fiber Optics Distributed Systems
Čučka, Milan ; Róka,, Rastislav (referee) ; Vlček, Čestmír (referee) ; Smékal, Zdeněk (advisor)
The dissertation is focused on the research of optical fiber sensors, which are based mainly on interferometric methods. The principle of operation of individual types of sensors is analyzed in the framework of simulation models, using several simulation tools. Furthermore, the possibilities of the coexistence of the sensor system within the planned or existing transmission networks are described. The possibility of accurate vibration measurement, localization of the vibration source and possibly temperature measurement is discussed. The measurements are mainly based on interferometric methods.

Interferometric measurement of phase changes of optical beam in turbulence
Děcká, Klára ; Křivák,, Petr (referee) ; Hudcová, Lucie (advisor)
This master’s thesis deals with the impact of atmospheric turbulence on phase changes of a free space optical signal. This problematic is investigated by the interferometric method. A part of the thesis is focused on the phenomenon of atmospheric turbulence. Then the physical effect of interference is discussed and optical interferometers are described. The experimental part of the thesis is focused on measurement of phase shift of optical signal by interferometric method. The result of the thesis is to determine how phase shift of an optical beam depends on the strength of turbulence.

Simulation of Mach Zehnder interferometer
Rozsypal, Filip ; Münster, Petr (referee) ; Čučka, Milan (advisor)
This bachelor thesis deals with the simulations of Mach-Zehnder and Michelson interferometer. These simulations are realized by VPIphotoncs and MatLab. The thesis also describes the optical and physical phenomena, the usage and the principle of operation of interferometers and results of measurements with validation of the basic work of both interferometers.
