Software library for signal transform and analysis
Skopalík, Daniel ; Prokeš, Aleš (referee) ; Maršálek, Roman (advisor)
Firm Elekt Labs s.r.o. is focused on data collection and analysis from machines usually in production industry. Firm use their own information system MASA (Measuring and Statistic Application) for data presentation and analysis. Goal of this bachelor thesis is implement new software functions which bring new features in data analysis. Most important new functions will be show derivation or integration of time variable signal. Also functions for signal oversampling, Fourier analysis, signal correlation and statistic correlation will be implemented.

Synthetic Holography
Tvarog, Drahoslav ; Chmelík, Radim (referee) ; Kotačka, Libor (advisor)
The thesis presents method of a creation of computer-generated holograms. The first part is devoted to an introduction of theoretical principles of a generation of synthetic holograms. The second part of the discourse deals with several practical methods of synthetic holograms creation. We present a computer code computing a discrete Fourier transform of an input image. The output of the code is an image matrix binarized in a specifically given way and printed on a transparent slide. When reconstructing the synthetic hologram we initially illuminate the slide with CGH by a plane wave and a reconstructed pattern is magnified through a camera objective to obtain a pattern observable by naked eyes. Finally, we analyze the quality of reconstructed pictures obtained from the synthetic holograms.
