Application of DIC method for measurement of deformations on small specimens
Vejchoda, Ondřej ; Houfek, Lubomír (referee) ; Návrat, Tomáš (advisor)
This diploma thesis tries to find the most suitable optical system for measuring deformation displacements on the surfaces of bodies. The first chapter describes the systems and methods that will be used. The second chapter is devoted to the design of the experiment. It describes the preparation of the experiment from the point of view of software and hardware and what are the important preliminary preparations. The last chapter contains the results of experiments and evaluation of the systems.

Optical design of telecentric F-theta objective
Perháč, Timotej ; Zámečník, Jan (referee) ; Antoš, Martin (advisor)
This thesis deals with optical design of f-theta lens for purposes of precision micromachining using a laser beam. Optical design consists of creating a nominal design according to specifications given by Meopta – optika s.r.o company and a tolerance analysis, which describes manufacturability of given design. Specifications given are most importantly diffraction limited image quality, correction of distortion throughout the field and telecentricity of systém in image space. F-theta lens in this thesis was created using an optical design software called Zemax.

Variants of the active triangulation technique
Sýkora, Vojtěch ; Richter, Miloslav (referee) ; Janáková, Ilona (advisor)
This thesis is about method called active triangulation, specifically about measure systems which using mirror in it. In thesis is explain principle of active triangulation and principles of other optic measuring technic. Then there is described design of measuring system, its calibration and finally the measurement itself. The possibility of using a telecentric lens for measuring systems based on the principle of active triangulation is also tested. All programs are written using MATLAB.
