Design of airsoft gun control electronics
Šindelář, Jiří ; Adámek, Roman (referee) ; Bastl, Michal (advisor)
This thesis deals with control electronics of airsoft gun type AR15. To create a prototype, it was necessary to select applicable components, design a printed circuit board, and create intelligent control software. Thanks to the designed electronics, the user will be able to fully control the behavior of his weapon.

Optical speed sensor of surface
Vaněk, Ondřej ; Hadaš, Zdeněk (referee) ; Sedlák, Petr (advisor)
The aim of this work is development of an optical sensor for surface-velocity measurement based on ordinary optical mouse sensor. The proposed sensor should have find its usage in industrial applications for low-cost contactless measurement of conveyor belts or semi-finished products, thus some other gauges could check quality of products. Theoretical part of this thesis includes introduction to optical sensors and their usage. Rest of the work describes practical part consisting of programming of communication between sensor and PC in MATLAB and Arduino environments, development of simple device based on Arduino hardware, the set-up of experimental workplace and providing speed tests.

Experimental work with POF - Polymer optical fibers
Doležal, Ondřej ; Urban, František (referee) ; Filka, Miloslav (advisor)
In this diploma thesis, the reader is familiarized with polymer optical fiber (POF). Firstly is mentioned theoretical background of optical fibers and optical transmission. The following are the basic properties and significant parameters of POF, a more detailed description of each type POF and their essential advantages and disadvantages in comparison with established optical fibers based on glass. The next chapter describes the area of practical issues: working with fibers and fiber installation, as well as the available connectors and methods of measurement of POF. Closely are analyzed knowledge of the practice, including the utilize in the aerospace and automotive industries, as well as in industrial networks, access data networks and local area networks. The practical part includes the measurement of basic transmission and mechanical parameters, including analysis of the results. The conclusion summarizes all the findings and results of this work, including possible future developments.

Optical sensor for UV radiation
Třešňáková, Andrea ; Drbohlavová, Jana (referee) ; Veselý, Michal (advisor)
This bachelor thesis deals with monitoring of photocatalytic activity on prepared optical sensors for UV illumination. A polymeric matrix was prepared based on the redox dye Acid Red 1, titanium dioxide and calibration agents. The deposition of matrix was done by material printing – roll-to-roll printer – on PET film. This resulted in optical dosimeter for UV illumination. Finally, the validity of the reciprocity law was proved.
