X-ray computed tomography fluoroscopy simulation
Bainar, Petr ; Kolář, Radim (referee) ; Drastich, Aleš (advisor)
The aim of this thesis is to create simulator of image reconstruction during x-ray computed tomography fluoroscopy. Simulator will be put to use in laboratory exercises concerning imaging systems. Introductory part is focused on description of x-ray CT imaging process. Emphasis is placed especially on specific fluoroscopic reconstruction algorithms. In following part of thesis, the concept of simulator is analyzed-its inputs and outputs are declared and user’s operation is sketched out. Consequently, appearance and controls of realized simulator are described in detail. In evaluative part of thesis, achieved findings are documented. Influence of process parameters on acquired images is described, in this part. Consequently, optimal preferences finding method is suggested. Manual for laboratory exercise is attached.

Preliminary design of imaging system without zoom
Melich, Radek ; Lédl, Vít
The aim of the report is to provide the preliminary design and simulations of an imaging system without zoom in accordance to the provided mechanical dimensions. The simulations will result in spot diagrams for various field objects. Finally, the optical transmission efficiency for optical design will be provided. All designed systems will be discussed with respect to their simulated performances and recommendation for final selected system will be provided.

Imaging system for spectrograph with multichanell Šolc filter
Rail, Zdeněk ; Lédl, Vít ; Jareš, Daniel
Solving the problem of solar spectrograph telescope,we have made research of possible imaging systems for spectrograph with multichanell Šolc filter.We have decided to use off-axis unobstructed Maksutov telescope,which is able to meet our demands for constant solar image scale in wavelenght within 380 to 760 nm.This telescope provides good image contrast similar to apochromatic objective lens uses only classical materials. Diameter of the telescope is 140 mm,focal length is 2000 mm.
