Optical position sensor
Jakubík, Tomáš ; Frýza, Tomáš (referee) ; Dřínovský, Jiří (advisor)
This thesis deals with optical sensors used in computer mice and their possible use as a 2D plane positioning sensor system. The first part of the thesis explains the principles and differences in function of individual sensors, as well as a description of the methods used to determine to position of the sensor. The thesis also addresses the possibility of such a sensor connected to a PC using a device to determine the position of the sensor. In the next part of this work the option to build such a device with the use of microcontrollers is described, including a description of the functions of various parts of the device. Last part of the thesis deals with the control equipment and software processing of information by a computer.

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.

Parametrization of PID controller on Mitsubishi PLC
Koláčný, Michal ; Bartík, Ondřej (referee) ; Blaha, Petr (advisor)
The aim of this thesis is to create a demo application for a brief introduction with the components of the PID regulator. The PID regulator is realized by a function block, which is implemented in a Mitsubishi PLC series iQ-F. The controlled variable is the height of the ping pong ball. The ball is kept at the desired height by changing the air flow rate. The change of the air flow is achieved by changing the motor speed. A propeller is mounted on the motor shaft which blows air into the tube. A SHARP GP2Y0A41SK0F optical distance sensor is built into the tube to sense the actual height of the ball. A model of this system is created and simulated in MATLAB program.The current information about the system is displayed on the Mitsubishi GT-2104RTBD operator panel, where it is also possible to change the sizes of individual parameters of the regulator.

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.

Special length sensors
Pavliš, Jakub ; Prostredník, Daniel (referee) ; Jankových, Róbert (advisor)
This bachelor thesis contains a theoretical description of selected length sensors with emphasis on inductive and optical sensors. The main benefit of this thesis is the design and realization of a special inductive sensor with a small pressure force and an optical sensor with a resolution of 2.5 nanometers. In the thesis are analyzed the selected metrological properties of the designed sensors and the formulation of recommendations for their practical use.
