Optical Field Evaluations for Hologram Synthesis
Fedorko, Matúš ; Polok, Lukáš (referee) ; Zemčík, Pavel (advisor)
The primary concern of this work is computer generated holography, in particular accelerating computation of synthetic holograms by means of modern-day massively parallel graphics chips. It starts by introducing fundamental holography principles together with mathematical and physical concepts behind it. Following discussion then deals with OpenCL, which is a relatively new, but well recognized standard for GP-GPU programming. Finally, the last two chapters of this work give an overview of problem analysis and its implementation in C++.

Optical Field Calculations in GP-GPU
Srnec, Erik ; Polok, Lukáš (referee) ; Zemčík, Pavel (advisor)
This work describes a relatively new technique designed to write highly parallel programs, that name is OpenCL. It is intended for both GPU and CPU and other parallel processors. Libraries used by the processor architecture, which includes a large number of small cores. These cores are not as comprehensive as conventional processors and is therefore suitable for calculations, which are many and they are simple. It is this property could, under certain conditions, accelerate the calculation of the hologram, namely the calculation of the optical field. While the calculation itself is simple, but the amount of processed data is large and therefore slow. The work also contain the basic concepts of explanation of optical and digital holography.

Holographic Hieroglyph
Sobotková, Adéla ; Havlíček, Jiří (referee) ; Cenek, Filip (advisor)
Topics fragmentary , symbolism and memory are the basic elements of creation and thinking Adele Sobotková (1987 ) . In her installation made of clay and covered with a udusaných objects together with the soil can walk, touch , read, intervene . This raises a cryptographic magical space full of mysterious objects in the video that represent clusters of personal hieroglyphic symbols and structures without the possibility of accurate decryption. These enigmatic characters are like glass or water , are changing , floating landscapes and refer to feelings of uncertainty, and forgetting the past, which is not entirely clear - is revealed as a mirage . Hologram is a representation of reality or reality that no longer exists but in time, or never existed , dream hi - technology , the current symbol of immortality, infinite and preservation in time. " Holographic hieroglyph " is a fluid phenomenon with varying meanings depending on its reading , the transcript or constant metaphor memories and the zpřítomňování hand in hand zpřítomňování a revival oblivion . Unclear character that has certainly not decipher , and yet we have it all in front of him , we see him from all sides , but also through him is the present and yet unreal . Great recording of uncertainty. (press release of the exhibition Holographic Hieroglyph in the Youth Gallery in Brno)

Holographic antenna
Klečka, Tomáš ; Polívka,, Milan (referee) ; Pokorný, Michal (advisor)
This master’s thesis deals with principle of microwave holography, methods of microwave hologram recording and analyzes some types of holographic antennas from structural and functional point of view. It also includes simulations of selected holographic antennas and their modi?cations, applies optimization on three types of antennas. Finally it reviews measured results of three costructed antennas.
