Fiber optic spectrometer
Krausová, Petra ; Münster, Petr (referee) ; Urban, František (advisor)
The purpose of this thesis is familiar with the problem of optical spectroscopy. The thesis describes the optical dispersion elements and spectral instruments. A separate chapter is devoted to Fourier spectroscopy, which in turn is based on a new technology SWIFTS described in the next chapter, in which the SWIFTS spectrometers compared with currently used spectral analyzers. The thesis then designs and evaluates experimental measuring which analyzes the detection of longitudinal distribution of radiation intensity in the optical fiber.

Emisivity and its Impact on the Heat Conductivity
Gančev, Jan ; Hejátková, Edita (referee) ; Szendiuch, Ivan (advisor)
This work deals with the issue of emissivity and its impact on the heat dissipation.The first part describes the basics of thermal management, the issue of emissivity and its measurement. In the second, experimental part, are dedicated the emissivity values of examined specimens. These values are then used as initial conditions for the thermal simulation. In the last part are compared the measured results and the simulated results and is evaluated the impact of emissivity for the heat dissipation.

Using the camera sensor in the measuring technique
Srba, Tomáš ; Čejka, Miloslav (referee) ; Bejček, Ludvík (advisor)
This bachelor thesis describes using of the Checkers in measuring technology, for control and picture comparing with picture reference by pixel match. Is describe part of machine vision as branch of industry automation. The bachelor thesis content summarized and described the basic methods, for image processing, function CCD and CMOS sensors, there are introduced standards of color signal encoding. Project this bachelor thesis is parameter checking of the checker. Special part of this work is description of working station for demonstration parameters checking of the checker. Program documentation of the Checker 101/E101 from COGNEX helps with design step by step.

Design of a spectrometer accessory for absolute reflectance measurements
Šustek, Štěpán ; Antoš, Martin (referee) ; Klus, Jakub (advisor)
This paper describes the design and the design solution of an extension for measurement of an absolute reflectance using Perkin Elmer Lambda 45. This paper is divided into three parts. The first part deals with the basic theory of optics, knowledge of which is necessary for the proper function of the optical components used in the design. The second part provides an overview of configurations used in the practice to measure both the relative and the absolute reflectance. The last section includes the final design solution of the extension.

Aircrew Dosimetry ů New Results, EC Projects Results
Spurný, František
The most of aircrew are exposed regularly to the effective dose exceeding 1 mSv per year, i.e. above limit for public as recommended in ICRP Publication 60. This is why different aspects of aircrew exposure have been studied since the beginning of 90Žs. Last development has been summarized by author recently; the contribution brings new achievements acquired during last 1-2 years, particularly in the authorŽs laboratory.
