Detection of acoustic vibrations using optical fibers
Skliar, Pavlo ; Dejdar, Petr (referee) ; Münster, Petr (advisor)
This bachelor thesis examines the possibilities of utilization optical fiber acoustic sensors. Introduction part describes the basic principles of signal transmission in optical fiber and the interaction of acoustic waves with optical fiber. Operational principles of different types of optical fiber acoustic sensors are explained further in the text.The fiber Mach-Zehnder interferometer is described in detail in this work. The work is focused on the possibilities of utilization single point and distributed optical fiber acoustic sensors. In the practical part, measurements were performed using a commercial optical fiber microphone and an implemented fiber Mach-Zehnder interferometer connected to a polarimeter.

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.
