Modeling of Inertial Sensors
Trličík, Jakub ; Klusáček, Stanislav (referee) ; Beneš, Petr (advisor)
This master thesis deals with measurement and modeling of MEMS inertial sensors. This paper describes basic principles of inertial sensors along with their most often errors. The next part shows results from inertial sensor market analysis, which enabling a selection of sensors to be measured. The following two chapters present methods for inertial sensor modeling and testing. The biggest part of text is dedicated to presentation of measurement results showing us static measurement of Allan variance, Earth rotation, temperature dependent bias and dynamic measurement of gyroscope sensitivity testing over temperature. In the last part of the thesis is presented a design of sensor error model by autocorrelation function and Allan variance and also an evaluation of achieved results.

Processing of digital signals from interferometer
Trličík, Jakub ; Čejka, Miloslav (referee) ; Havránek, Zdeněk (advisor)
Abstract This bachelor thesis deals with the S/PDIF digital signal processing from interferometer Polytec OFV-5000, by measurement application created in LabVIEW. This paper describes the theory of laser vibration measurement and encoding S/PDIF digital signal. Text also introduces a Polytec system for vibration measurement and system for data acquisition by National Instruments. The following is a description of the created measurement application, divided into three parts: decoding an S/PDIF, acquisition and display of digital data and acquisition and display of analog data to compare with digital output. In the last part of the thesis are presented the results of comparing analog and digital output, and an evaluation of the achieved results.
