Surface analysis using low-coherence interferometry
 Pikálek, Tomáš ; Novák, Jiří (referee) ; Buchta, Zdeněk (advisor)
This thesis deals with low-coherence interferometry, laser interferometry and its combination intended to be used for contactless surface analysis. It outlines theoretical background of laser interferometry and low-coherence interferometry and describes in detail interference fringe center detection techniques used in low-coherence interferometry and their implementation into MATLAB environment. All these techniques theoretically described were analyzed to evaluate their measurement accuracy, resistance to optical dispersion and computational complexity in order to choose the most appropriate technique to be involved into the experiment. Furthermore, the thesis describes design of an experimental setup for optical surface analysis combining laser interferometry and low-coherence interferometry. There are presented experimental results and its comparison with the reference measurement. Overall measurement uncertainty is calculated and discussed too.
