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.

Optical Field and Hologram Synthesis
Šulgan, Marián ; Seeman, Michal (referee) ; Zemčík, Pavel (advisor)
The main focus of this work is to implement appropriate chosen method of optical field synthesis in several forms, compare their results and confirm its validity by reconstruction of hologram generated from calculated optical field. For its complexity and demanding calculations, various accelerations are employed - linear approximation, parallelization, using technology C++ AMP, which facilitates opportunity to use GPU for massive parallelism. The work begins with explanation of basic holography principles followed by design of application offering solutions to set problems. The final part explains the implementation of application programmed in C++, testing process, gained results and their evaluation. The text ends with final conclusions regarding completion of set tasks and possible future expanding or improving.

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++.
