"Fisheye" Camera Projection
Macík, Pavel ; Juránek, Roman (referee) ; Seeman, Michal (advisor)
The thesis describes theoretical fundamentals of optics and problems of ray-tracing method, ray-triangle intersection computation included. Next section describes concept of three different camera models for ray-tracing method - plain camera, pinehole camea and spherical camera (fish-eye). The thesis comparse properties and capabilities of camera models and their effect to projected image of a scene. The program for raytracing was implemented for purposes of the thesis including implementation of camera models described in the thesis.

Local IR spectra measurement system
Pospíchal, David ; Trčka, Tomáš (referee) ; Škarvada, Pavel (advisor)
The diploma thesis deals with the design of a system for measuring infrared spectra from local areas of samples. The theoretical part describes the electromagnetic waves and related phenomena. Furthermore, the semiconductor junction and solar cells are discussed. The following is a basic description of line spectrometers. In the practical part, a suitable arrangement of the whole system, collimator design, and especially the core of the whole work, ie control software and signal processing, are proposed.

Water in physics and physics in water
BREBURDOVÁ, Hana
Breburdová, H. (2022): Water in physics and physics in water. Diploma thesis. České Budějovice: University of South Bohemiain České Budějovice, Faculty of Education. This diploma thesis focuses on research-based teaching and the creation of physics experiments fit for teaching physics at the lower-secondary level of education. The primary goal of this thesis is to suggest certain physics experiments that, while allowing the use of water, also explain the basic behaviour of liquids in physics. Furthermore, it aims to create a worksheet for realised research-based. The outputs of this are selected experiments and a worksheet of research-based teaching.

Precise bonding of composite materials
Tellinger, Adam ; Gregor, Lukáš (referee) ; Kupčák, Radim (advisor)
This bachelor's thesis deals with the issue of bonding composite materials. The first part of the bachelor's thesis is focused on research into the production of composite materials and gluing technologies. The content of the practical part is the design of test specimens and a preparation for their bonding with subsequent production. Furthermore, verification of compliance with the required accuracy of bonded joints when using different adhesives using 3D measurements.

Influence of surface roughness on optical properties of machined materials
Ashqar, Ghaith ; Jaroš, Aleš (referee) ; Kupčák, Radim (advisor)
První, teoretická, část této bakalářské práce se věnuje problematikám souvisejícím s výrobou mechanických položek pro optické přístroje. Poskytuje úvod k parazitnímu světlu a přehled způsobů jeho eliminace. Následuje obecná část zabývající se soustružení a sekce věnovaná měření drsnosti povrchu. V praktické části jsou tyto poznatky zúročeny v podobě návrhu a následné výroby prototypového vzorku který bude sloužit k vyhodnocení vlivu drsnosti povrchu na množství parazitního světla v optickém přístroji. Drsnost povrchu jednotlivých vzorků byla změřena a porovnána s teoretickou hodnotou získanou výpočtem. Prototyp byl vyvinut v úzké spolupráci s R&D oddělením přerovské firmy Meopta – optika, s.r.o. Na základě budoucích zkoušek a měření bude vyhodnoceno, zda je autorem navrhovaná inovace aplikovatelná v oblasti přesné mechaniky a optiky.

3D reconstruction
Vít, Luboš ; Honec, Peter (referee) ; Richter, Miloslav (advisor)
The thesis focuses on 3D measurement using line scan cameras. In response to the emphasis on quality and automatization of production nowadays, the line scan cameras are the appropriate devices providing accuracy for a belt product inspection. The first part of the thesis discusses the desing theory of optics, sensoring and image processing. The realisation of designing a mathematic instrument for evaluation of 3D shape, designing a test workspace and the main sensoring of the scene with processing with basic measuring algorithms is a content of the second part of the thesis.

Magneto-optic response of layered media
Kunt, Ota ; Ostatnický, Tomáš (advisor) ; Antoš, Roman (referee)
Optical response of materials strongly depends on their magnetic properties. This phenomenon is also used in materials in the form of thin layers and multi- layers. Using cited literature we summarize theory needed to calculate magneto- optical response of multilayers. The calculation is based on Maxwell equations and magnetic materials are described with effective permittivity tensor. Jones formalism is used to describe polarised light and Yeh formalism is used to de- scribe multilayer response. A program using presented theory was developed and calculations for concrete structure were made. Multilayer parameters were cho- sen to correspond with those of a sample whose magneto-optical response was measured at the Department of Chemical Physics and Optics, MFF UK. 1
