Biological analysis in NIR
Pirkl, Petr ; Janoušek, Oto (referee) ; Čmiel, Vratislav (advisor)
This bachelor thesis is focused on obtaining information about analyzes by IR radiation. It also deals with the effect of IR radiation on substances and the principles of functioning of IR spectrometers. There are examined coffee samples in the work. Usefulness for discrimination caffeine and decaffeinated coffee is tested. Next, flour samples are researched. There is examination of presence or absence of gluten.

Thermal measurement of the building
Kozák, Karol ; Mauder, Tomáš (referee) ; Štětina, Josef (advisor)
Infrared measurements, as a method of contactless temperature measurement, has spread rapidly in various branches of industry. Nowadays, in era of saving energy and financial resources spent on building heating, it has become an inherent part of revisions and controls of excessive heat transfer over thermal bridges. The aim of this bachelor's thesis in it's first part is to describe the theory of infrared measurement and heat transfer of the building and the second part is focused on application of theoretical knowledge to evaluate the results of practical measurements of buildings A2, A3, A4 and A5 on Faculty of Mechanical Engineering, Brno University of Technology, which is regulated by the technical standard ČSN EN 13187.

IR thermometer with automatic emissivity correction
Dobesch, Aleš ; Tannenberg, Milan (referee) ; Poliak, Juraj (advisor)
Diploma thesis deals with basic physical quantities and laws relating to non-contact temperature measurement and emissivity determination of solids. It describes the design and implementation of the IR (Infra-Red) thermometer often missed with automatic emissivity correction. The first chapter explains the concept of temperature and basic principles of temperature measuring . The second chapter focuses on the history and theory of non-contact temperature measurement. Gradually are explained the concepts related to non-contact temperature measurement and the problem of determining the emissivity of the body. Next third chapter describes the proposed hardware solution of IR thermometer. The fourth chapter describes a software written for the IR thermometer. The fifth and last chapter summarizes the findings and knowledge from the implementation of non-contact thermometer and measuring emissivity.
