Design and Simulation of Micro-Bolometer in MEMS Technology
Svatoš, Vojtěch ; Pekárek, Jan (referee) ; Hubálek, Jaromír (advisor)
Tato diplomová práce zkoumá problematiku detektoru infračerveného záření nazývaného bolometr. Cílem je pokrok v detekci infračerveného záření použitím odlišné absorpční vrstvy modifikovanou karbonovými nanotrubicemi. V teoretické části jsou uvedeny základní fyzikální pojmy z problematiky teplotního managmentu a základních fyzikálních vztahů bolometru. Design bolometru je představen a popsán. Teplotně mechanické simulace předvídají chování bolometru při detekci infračerveného záření. PSpice model je vytvořen a kombinuje termální a elektrické vlastnosti čipu bolometru. Dále je uveden proces výroby bolometru, které je detailně popsán.

Optical device for breath CO2 concentration analysis
Škorpík, Daniel ; Milek, Jakub (referee) ; Čmiel, Vratislav (advisor)
This Master's thesis discusses about the measurement of the carbon dioxide concentration in breathing by an optical analyzer using infrared absorption spectroscopy. The method is described with the technical focus on individual components needed for subsequent implementation. A circuit diagram is created to produce Arduino platform devices that serve as hardware to connect and power individual parts and software to create a user environment, followed by a Bluetooth module to transmit measured data to mobile devices where real-time results are presented.

Technical bases of thermography for radiologists.
SOSNA, Filip
The bachelor thesis solved the technical fundamentals of thermography using the curriculum process. The bachelor thesis has investigated the problem in the following way: Goal 1: Perform a system analysis of the technical bases of thermography and adapt the results to the capabilities of radiological assistants - Goal 1 was accomplished by performing a system analysis of the structural levels of the technical bases of thermography. Goal 2: Perform a comparative analysis of the technical bases of thermography abroad and in the Czech Republic - Goal 2 was met by comparison between America, Asia and Europe and the Czech Republic (with an unsuccessful result for the Czech Republic). Goal 3: To transform the results of system analysis, adapted to the needs and possibilities of future radiological assistants, into educational form - goal 3 was fulfilled on the basis of selected educational theory and its application. Goal 4: Choosing a suitable educational theory to convey knowledge about the technical bases of thermography to radiological assistants - Goal 4 was accomplished by selecting the theory of the curricular process. Hypothesis H1: Educational form of the technical basics of thermography for the examined group of recipients can be created by applying the theory of curricular process - Successful implication of individual variant forms of the curriculum on the research field of technical basics of thermography enabled the hypothesis H1. Hypothesis H2: Knowledge of the recipients of education in the field of technical basics of thermography will have a Gaussian distribution close to the implemented distribution curriculum - Successful application of selected types of theoretical distributions (exponential distribution, normal distribution) to the result of the educational test. The theoretical benefits of the thesis include the design of structural levels of the system of technical basics of thermography. The practical benefits of this thesis include, for example, creating an educational text and a test for the technical basics of thermography. Based on the achieved results, it is also possible to propose follow-up work - eg exploring the possibilities of increasing the use of thermographic imaging methods in the Czech Republic.

Technolgy of materials preparation for the high sensitivity infrared detectors
Novotný, Jan ; Zelinka, Jiří ; Franc, J.
Single crystals of triglycine sulphate (TGS) doped with L-alanin, lysin and with Co.sup.2+.sup., Cd.sup.2+.sup. and PO.sub.4./sub..sup.3-.sup. were grown from aqueous solutions by means of slow cooling method. Concentration of doping elements varied from 5 to 20mol. per cent. Morphology, domain structure and P-E hysteresis loops have been investigated. TGS single crystals doped with Co.sup.2+.sup. and PO.sub.4./sub..sup.3-.sup. show the inernal fields as high as 217 kV/m with peculiarities in the hysteresis loops. The best hysteresis loop has been obtained on TGS crystal doped with Lysin and Cd.sup.2+.sup. ions.
