Optical fiber point sensors
Okoun, Petr ; Čučka, Milan (referee) ; Urban, František (advisor)
This diploma thesis analyzes a structure of spot optical sensors with longitudinal grid and multiple Bragg grating and possibilities of spot optical sensors use and implementation in the industry. Basic principles of light propagation through optical environment are described in the introduction part, followed by description of phenomena in optical fibers and sensors. The distribution of fiber optic sensors and the use of optic fiber in spot mode is described further. The optical sensor system is designed on the basis of analysis with description of its construction at the end of this work. A significant part is devoted to the analysis of longitudinal structures in the fiber in response to multiple Bragg gratings, their subsequent manufacture and suggestion of use in sensors industry.

Electronic Compass Based on Three-Axis Magnetometer
Okoun, Petr ; Povalač, Aleš (referee) ; Šebesta, Jiří (advisor)
This semestral thesis deals with development of electronic compass with three-axis magnetometer which eliminates deficiencies of magnetic compass and then the developed device is usable anywhere at Earth's surface around the world. A compass is able to measure the azimuth only if its position is horizontal. Bearing in mind that this condition cannot be satisfied in any case, the solution of compass tilt compensation using accelerometer is part of the project.
