Measurement of optical lenses parameters
Wintr, Aleš ; Coufalíková,, Aneta (referee) ; Hudcová, Lucie (advisor)
This paper contains a basic overview and description of optical lenses. It introduces different types of optical lenses and shows how they influence the passing of light beams. It deals with the production of optical lenses and their practical use. It describes types of optical blemishes that exist in real optical systems. Particular attention is given to parameters of optical lenses and their measurement in practice. It includes a Matlab program to calculate parameters of optical lenses derived from the measurements.

Model of the Surface Optical Intensity Distribution in the Beam
Wintr, Aleš ; Hudcová, Lucie (referee) ; Wilfert, Otakar (advisor)
The aim of the thesis is first to describe the light beam spreading through free space and its characteristics. The theoretical part of the thesis developed programs that display models of beams. Given the parameters, theses models depict areal dispersion of optical intensity in the cross-section of beams. More specifically, I developed both a 2-dimensional and 3-dimensional model of beam depiction and a 3-dimensional model with variable angle of rotation of the beam trace. For this purpose I used the software Matlab R2007a. In the experimental part of the thesis I assembled a measurement chain and measured optical intensity of selected optical fibre. The measurement chain included laser Promax Prolite 80, optical source LED Promax Prolite 81, optic power meter Exfo 67A, collimator Thorlabs F810FC-1550 and optical fibres with various characteristics. The measured values were used to plot graphs depicting aerial dispersion of optical intensity and these graphs were compared with the theoretical computer model developed in the theoretical part of the thesis.
