Remote fault monitoring system
Jarůšek, Jakub ; Trčka, Tomáš (referee) ; Škarvada, Pavel (advisor)
In practice, optical non-contact measurement of distance and displacement is divided into various methods that use a different parameter of the optical (light) signal. Some methods are explained in the work. The triangulation method is described in more detail. This method is used to measure and monitor the displacement of geological faults. For this monitoring, a low-budget device is designed, which uses lasers and a sensor to determine the displacement of the measured object in a certain time interval. The whole system will serve as verification of data measured by magnetoresistive sensors.

Monitoring of hazardous environment
Bilík, Martin ; Blecha, Radim (referee) ; Blecha, Petr (advisor)
Diploma thesis Monitoring of hazardous environment deals with possibilities of construction of monitoring device for the nuclear power station Temelín. In the first part are accurate requirements for monitoring device, individual risks and identify obstacles and opportunities how to overcome them. There is also description of basic options for measuring temperature and environmental monitoring. Using multi-criteria analysis was done the selection of all components, from which is possibility to construct the first development release of monitoring device. 3D models for each component and the overall design visualization facilities were created in the programming environment of Autodesk Inventor. The conclusion provides an overview of the financial cost of the equipment is assembled

Use of the DIC method in solving basic problems of solid mechanics
Hrůza, Vlastimil ; Pokorný, Jan (referee) ; Ščerba, Bořek (advisor)
This bachelor’s theses deals with the solution of basic problems of solid mechanics using digital image correlation. The research part of the thesis presents some of the optical methods used for deformation measurement, digital image correlation in particular, whose history, principles, limitations and utilizations are described in detail. In the practical part of the theses, three experiments are carried out, which are then evaluated using digital image correlation and the results are compared with the created computational models. In the first experiment, strain on the tensile test specimens with notches is measured, the second experiment is focused on measuring strain when bending curved beams and in the final experiment, natural frequency of a fork produced by 3D printing is determined.

Contactless measurement of temperature
Smrž, Martin ; Rozman, Jiří (referee) ; Balogh, Jaroslav (advisor)
Purpose of this bachelor thesis is get acquainted with problem of non-contact measuring of surface temperature of human body. The teoretical part of this labour deal about physical substance of non-contact temperature measurement, using types of detectors and application of this method to the medicine. In the practical part will focus on design and realization of electrical circuit for non-contact temperature measuring, comunication with personal computer and software solution of program for building surface temperature map of patient. At the end of labour was performed a set of measuring to compare accuracy of built thermometer with commercially available products.
