Controlling of camera
Tylš, Ladislav ; Valach, Soběslav (referee) ; Richter, Miloslav (advisor)
This thesis describes the principles of making application which is able to set and control camera. The first part describes basic camera connections and it explains definition and specification of camera’s features. The second part of my thesis describes implementation of application, which can use more cameras to image preview, image acquisition and to simply set of camera’s features. To implement the applications we can use MATLAB and C++BUILDER uses opencv libraries.

Optical spectrometer designing
Dohnal, Marek ; Křivák, Petr (referee) ; Hudcová, Lucie (advisor)
This project focuses the problems of projection and design of optical instruments being instrumental to determination of elements in various material compounds. There are described here the structures of fundamental optical instruments and their possible variants, one of which has been chosen and further entered into details. The work specifically refers to an optical spectrometer, which by its nature, ranges the bands both of visible and near-infrared radiation. The work presents basic principles of particular parts, which the existent instrument can consist of, the advantages and disadvantages brought by the single parts. For specifically proposed configuration, intentionally set in such a way it uses state-of-the art measurement methods obtaining the best possible measurement results, the work analyzes in details the method of operation and solves numerically the theoretical assumptions for correct operation of the spectrometer. A constituent of the project is an experimental measurement testifying, with certain errors, to the theoretical solutions. The measurement errors that could result from chosen arrangement and chosen measurement method are numerically expressed in a separate sub-chapter. Further various calibration methods are mentioned, based on which the calibration method used during the experimental measurement was selected. The last part of project is focused on circumferential design of the optical spectrometer, where series of suitable circumferential elements was scrutinized. For basic elements there are presented their parameters and possible troubles related to the implementation. Furthermore the realisation of project was carried out and the spectrometer was assembled with the parts available in laboratory. The results were elaborated with a computer programme created specially for this application and then compared to a professional spectrometer.

Accurate controll of piezoactuator
Hurdálek, Tomáš ; Šifta,, Radim (referee) ; Urban, František (advisor)
This thesis deals with the possibility of current and voltage control of piezoactuators from the point of view of control of optical filters for retuning the optical spectrum. At first, there is an effort to clarify the basic physical principles that are closely related to this issue. The thesis also deals with different types of piezoactuators and determines which one is the most suitable for the application. Attention is also paid to the explanation of different control options. A comparison of available drivers was made. Measurements, circuit simulations and testing of various circuits of critical parts of the driver were made. Based on this, a current driver and a current source to power it were developed. The device has been constructed and tested.
