Automatic measurement of LED spectrum
Žabka, Jindřich ; Hudcová, Lucie (referee) ; Skryja, Petr (advisor)
Teoretical part of the thesis is introducing light sources. Here are examinated the principles of light generation in these light sources, basic radiometry and photometry variables, according to which are these sources sorted and their operating parameters. The parameters describing quality of light sources are also mentioned here. Next part examinates LEDs, theirs usual construction types and most common SMD LED packages. Part about optical spectroscopy describes usually used components for optical measurement. Practical part narrates appropriate organization of workplace, LabVIEW platform, communication process with instruments and a guide describing measure process. There is a solved laboratory protocol as an attachement.
Automatic testing of gas leak detector
Skryja, Petr ; Malinowski, Radim (referee) ; Novák, Marek (advisor)
This work deals with the automatic testing of an ultrasonic gas leak detector, which has to be tested during normal changes in the development phase. The reader will be acquainted with the basic principles of gas detection, design of the test product, software architecture its implementation. The following is a presentation of the application and instructions for writing tests. In this work, the Beaglebone Black development board with the Debian operating system is used as the core of the entire test product.

Adjustable Laboratory Power Supply
Skryja, Petr ; Kubíček, Michal (referee) ; Šebesta, Jiří (advisor)
The aim of this work is to enlighten the reader with topic of linear power sources and guide him through designing his own adjustable laboratory power supply. Design of adjustable laboratory power supply uses the stabilizer L200 with voltage regulation and current limitation. Device is expanded with digital part (using ATmega8 MCU) to enable peripherals control and measured values processing. The laboratory power supply will be constructed and its parameters will be measured.

The System For Laser Beam Tracking And Communication
Skryja, Petr
The paper describes a system for laser beam tracking and communication with using one optical laser beam. As an active receiver element, improved tetra-lateral two-dimensional position sensitive detector S5991-01 is used, which is used both to obtain beam position and to receive transmitted data. A laser with a wavelength of 650 nm is used for data transmission. The transmitted data are coded with Manchester code. Position calculation, data receiving and transmitting is carried out by development board STM Nucleo H743ZI.

Device For Automatic Testing Of Ultrasonic Gas Leak Detector
Skryja, Petr
In this paper a device for automatic testing of the gas leak detector is presented. The device allows testing product which is an embedded device that is improved during a development. This requires testing the product after each implementation of a new feature, as there may be situations where this implementation will stop some part of the product from being functional. For realization mini PC Beaglebone Black was used and software architecture of this device is introduced.The presented device is able to do automatic testing that is more accurate and faster than human testing.
