Design of optical fiber sensor for vibration detection
Janoušek, Adam ; Münster, Petr (referee) ; Dejdar, Petr (advisor)
The master theses deals with a detailed analysis of optical fiber sensors. Specifically, there are discussed optical fibers, various types of sensors and realization optical fiber senzor and senzor system that has been optimized and processed data in real time. In master theses also describes the LabView programming enviroment and uses components, including the entire sensor systém of a sensors system that sends measured data

Laser coupling system
Dell, Roman ; Wilfert, Otakar (referee) ; Barcík, Peter (advisor)
This bachelor's thesis deals with the usage of a tunable pulsed laser for coupling to a single-mode fiber. At first, the thesis explains the principle of laser functioning, its basic technical components, properties of laser radiation and main types of tunable pulsed lasers. Next, it describes main types of optical fibres, their key properties and the methods for laser to fibre coupling. Finally, the thesis explains the basic concepts of matrix optics, its application to the Gaussian beam transformation and the calculation of coupling efficiency.

Long optical fibre routes influence on the polarizing state of light and uses it for powering polarization sensors
Panascí, Marco ; Grenar, David (referee) ; Filka, Miloslav (advisor)
This diploma thesis deals with the influence of long fiber optic paths on the polarization state of light and their use for powering polarization sensors. The aim of the diploma thesis was to design the arrangement of optical fiber components so that the polarization properties of light at the end of the path are further usable for sensory purposes. Four partial measurements with a long path (in a laboratory setting, laying in the ground, on a curtain, under the influence of external influence) and one measurement without a path under the influence of external influence were designed. The overall measurement results demonstrate that for the functional power supply of long-distance sensor systems, an existing single-mode fiber can be used (laid by laying in the ground), into which a light source for a given sensor system would be multiplexed. In the discussion, all types of measurements are analyzed and compared with each other. Finally, the overall result is summarized and applications are described in which such a sensor system could be used.

Laboratory exercise: Modeling of photonic communication networks
Kovaříková, Hana ; Horváth, Tomáš (referee) ; Münster, Petr (advisor)
The bachelor’s thesis deals with the issue of modern high-speed data networks and their simulation in the MATLAB Simulink environment. The theoretical part is devoted to optical networks, fibers, their properties and standards. The thesis also explains the subject of passive and active optical networks, including their components. Laboratory tasks are devoted to the simulation of the transmission of a passive optical network with a splitter and an active optical network with an amplifier.
