Methodology for contactless measurement of temperature
Skalický, David ; Rozsívalová, Zdenka (referee) ; Frk, Martin (advisor)
This thesis deals with the issues of contactless measuring of temperatures and calibration of chosen temperature meter. The beginning of this thesis concerns physical laws and basic terms which are crucial for contactless measuring of temperatures. The following part gives the division of detectors and pyrometres for contactless measuring of temperatures. The conclusion of the theoretical part describes the advantages of these ways of measuring and practical use of them. The practical part deals with instruments that are accessible at Faculty of Electrical Engineering and Communication, their comparing and choice of the most advantageous meter for calibration. The following part is the implementation of the experiment related to contactless meassuring of temperatures. The conclusion of the practical part contains composition of optimized workplace for calibration of contactless temperature meters and the calibration of chosen temperature meters itself.

Thermal phenomena modeling of air electronic unit
Ančík, Zdeněk ; Toman, Jiří (referee) ; Vlach, Radek (advisor)
This thesis is focus on thermal analysis of aircraft electronic devices and their cooling possibilities. The two analytic methods of thermal analysis are applied on two particular technical objects. The laboratory experiment of non-contact temperature measurement method is applied on real unit. The results of simulation are compared with results of experiment.

Methods for infrared thermography with detection of specific facial areas
Kolářová, Dana ; Bernard, Vladan (referee) ; Maryšková, Věra (advisor)
This paper deals with non-contact measurement of temperature in human faces. Principle of measurement of infrared radiation and construction of the thermal imager is described in a literature search. The main part of the paper is design of an algorithm for automatic processing and the detection of regions of interest in thermal images. The theoretical description of used methods is also included in this paper. The aim is to design and implement a program for automatic evaluation of temperature changes in a human face in a sequence of thermal images that were taken with short time delay. As a part of thesis is description of implementation of designed algorithm in programming enviroment MATLAB and the description of the user interface. The program was tested on the experimental data samples. Obtained results and possible limitations are also discused in this paper.

Accuracy of body temperature measurement using infrared technologies
Mezera, Jiří ; Chmelař, Milan (referee) ; Provazník, Ivo (advisor)
This thesis deals with the measurement of body temperature using the infrared thermometers. The literature research is devoted to the description of the human body temperature, methods of its measurement and types of thermometers. The theoretical part further examines the infrared radiation, the principles of measurement, physical quantities, laws of infrared radiation, types of detectors and measurement uncertainties. The practical part focuses on experimental measurements with selected kinds of thermometers and verifying their accuracy. Finally, an experimental procedure has been designed which has then been used for the clinical measurements of body temperature under various conditions and their subsequent statistical evaluation.

Temperature measurement of a machine tool
Sloboda, Tomáš ; Kovář, Jiří (referee) ; Hermanský, Dominik (advisor)
The aim of this thesis is to get acquainted with the theory of temperature measurement, various kinds of contact and non-contact gauges, their construction and accuracy. It also tries to explain the basic knowledge of machine tools and their thermal load. Part of the work is to test this knowledge with experiments in the company Intemac Solutions s.r.o. and Faculty of Mechanical Engineering at Brno University of Technology. The obtained results are further evaluated and compared with the help of graphs and tables. To process the obtained data from the sensors, program Labview was used and FLIR Tools was used for thermal pictures taken with thermal camera. During evaluation, it was also necessary to consider measurement errors caused by the factors resulting from the physical laws described in this work.
