Cyclic Helicoid
Přikrylová, Ivana ; Chvalinová, Ludmila (referee) ; Borecká, Květoslava (advisor)
Cyclic helicoids belong to the descriptive geometry. The aim of this work is to demonstrate the cyclic helicoids and their use in engineering practice. First of all we will deal with the movement of screw, helix and its tangents. Then we will describe the general area, and cyclic helicoids. Cyclic helicoids split the position of the surface forming a circle relative to the axis of screw motion. Images complement the all important processes and geometric data. Images are drawn by the program Rhinoceros. Finally, we evaluate the use of cyclic helicoids in various fields and in everyday life.

Design of projection illuminator
Přikrylová, Ivana ; Vacula, Daniel (referee) ; Antoš, Martin (advisor)
The aim of this diploma thesis is to design a suitable reflector concentrating a light beam into a circular hole in a gobo. The light beam behind the screen should have good efficiency and at the same time good homogeneity. For the reflector design and analysis a software for designing optical systems called LightTools was used. The reflector was designed by six different methods. Several smooth and several faceted reflectors were designed. The selected reflector was analyzed in combination with a varifocal lens. For selected reflector was designed mechanical store with respect to the anticipated operating conditions. This thesis serves as the basis for the producing of the reflector.
