Gaussmeter design with three-axis measuring probe
Hejtmánek, Tomáš ; Novák,, Miroslav (referee) ; Roubal, Zdeněk (advisor)
The purpose of this work is the design of a gaussmeter with a three-axis probe for magnetic field mapping and subsequent reconstruction of the image using magnetic impedance tomography. Commercially available gaussmeters have low bandwidth for these purposes, and signals cannot be measured in synchronous detection mode. The aim of the thesis is select the most suitable magnetic field sensors for the MIT purposes and to design the entire measuring device to meet the measurement requirements in the wider frequency band and synchronous detection. Attention will also be paid to designing a suitable mechanical design of the probe and the location of the sensors. The proposed device will be tested and evaluated for MIT purposes.

Application for magnetic field mapping using F.W.BELL 9950
Kohnheiser, Jan ; Kubásek, Radek (referee) ; Hadinec, Michal (advisor)
The aim of this project is to acquaint the reader with the possibilities of controlling gaussmeter FW Bell 9950 by computer. The thesis analyzes the problems of measurement of magnetic flux density and the measuring instrument itself and its ability to communicate with the PC will be introduced. Next part of the thesis deals with the description and control of the application designed for communication and mapping magnetic field with F.W. Bell 9950.

Measured Parameters Of The Three-Axis Gaussmeter
Hejtmánek, Tomáš
The purpose of this article is a measuring parameters of a gaussmeter with a three-axis measuring probe designed for magnetic field mapping. Commercially available gaussmeters have low frequency bandwidth for these purposes, and signals cannot be measured in synchronous detection mode. Therefore, a suitable magnetic field sensor was selected and one channel of the device was designed and made. In particular, the higher bandwidth for three-axis measurement and the possibility of synchronous signal detection were taken into account. Attention will also be paid to designing a suitable mechanical design of the probe and the location of the sensors. The gaussmeter will be used for magnetic impedance tomography (MIT), which is reconstruction method of conductivity image. On the proposed device was performed measurements of frequency bandwidth, noise measuring of Hall probe and measuring constants of Hall generators. The properties were evaluated and compared with parameters of commercially available Gaussmeters.
