Design of the method to increasing of accuracy of the tunable optical filter optical spectra measurement
Jelínek, Michal ; Holík, Milan (referee) ; Mikel, Břetislav (advisor)
The thesis deals with the method for the improvement of the measurement accuracy in the optical frequency spectra measurements based on tunable optical filters. The thesis starts with the selection of the proper optical filter that is suitable for accurate light spectrum measurement. The selected filter was then used for the design and realization of the measurement system for the inspection of the fibre Bragg gratings. The system incorporates a reference block for the compensation of environmental influences, an interferometric verification subsystem and a PC - based control software implemented in LabView. The preliminary experimental verification of the measurement principle and the measurement system functionality were carried out on a testing rig with a specially prepared concrete console in the UJV Řež. Advanced tests were conducted on nuclear power plant’s containment shape deformation measurement in Temelin.

Design of the optofiber sensor system to monitoring change of length
Jelínek, Michal ; Stehlík, Jiří (referee) ; Mikel, Břetislav (advisor)
The bachelor´s thesis deals with design and verification of optical fiber sensor system for measuring changes of length. This system is designed to shape monitoring of the nuclear power plant containment. The principle of measurement, design and realization of the first version is described in the work. Principle of measurement and functionality of the whole system was verified by measurement of specially prepared reinforced concrete console. The console was prepared in the way to simulate behaviour of containment of the nuclear power plant. Within development of system there were prepared of optical fiber sensors with Bragg´s grattings which are later used for measurement.
