Influence of imaging sensors properties on the quality of the quantitative phase image reconstruction
 Šulc, Václav ; Antoš, Martin (referee) ; Dostál, Zbyněk (advisor)
This bachelor thesis is focused on imaging sensors noise characteristics and their impact on quantitative phase imaging. From available sensors the darkframes were acquired and analyzed. Computed data of noise standard deviation were used to simulate synthetic holograms for reconstruction of quantitative phase images. A camera Basler acA2040-180km was found to be a most suitable device for holography. The design, fabrication and testing of an effective cooling system for such a device proved to have even better noise characteristics.

Numerical simulation of the laser light scattering from rough surfaces
 Šulc, Václav ; Klapetek, Petr (referee) ; Ohlídal, Miloslav (advisor)
A Matlab numerical model for scattering simulation was proposed based on the solution derived from the Beckmann-Kirchhoff scalar theory of scattering of electromagnetic waves from rough surfaces. A series of various synthetic surface samples were obtained using the open source software Gwyddion on which numerical simulations of scattering were carried out. The validity of this numerical model was tested and compared with experimental results.
