Control system for Eurotherm controller
Kostka, František ; Krechler, Jindřich ; Ronovský, Petr
Software for measuring secondary luminiscation is described. Software can switch power grades of heating and can gain actual temperature from Eurotherm controller.
Software radio in the mobile radio-communication /telephony/
Ďurovič, Svetozár
In the paper various applications of software radio in wideband mobile telephony systems are presented. The architecture of the basic parts of the mobile systems 3G is described and special attention to the technical problems is given. The report contains many computer programs to illustrate the mathematical procedures.
Chromatic dispersion measurement of optical fibres using interferometric technique
Dymák, Pavel ; Peterka, Pavel
Research report deals with measurement of chromatic dispersion of singlemode optical fibres using interferometric technique at IREE AS CR in Prague. The document describes in details all components of measurement setup, initial setting up and measurement procedure, using of assembled control programs and the measurement data processing too. Several tips and practical recommendations complete the report based on many performed experiments.
2003 Program of Development. Final report on Project M/19/03: Primary metrology of time and frequency
Čermák, Jan ; Buzek, Otokar ; Čemusová, Blanka ; Šojdr, Ludvík
The report brings a summary of the results obtained by The Institute of Radio Engineering and Electronics (IREE) in the field of primary time and frequency metrology realizing the M19/03 project of The Metrology Programme of the Czech Office for Standards, Metrology and Testing in 2003.
Photodynamic therapy. Instrumental optics
Votruba, J. ; Stádník, Bohumil ; Javorský, Stanislav
Photodynamic therapy of cancerous tumorous of various human organs uses both coherent and noncoherent light sources for the treatment. However, noncoherent ones are prefered due to higher treatment efficiency, simpler and reliable operation and lower financial costs. Main purpose of this report is to give overview of basic optical methods and instruments used in the photodynamic therapy.
Preparation and properties of pyroelectric detectors for optoelectronic applications /III/
Novotný, Jan ; Zelinka, Jiří ; Podvalová, Zdislava ; Malina, Václav ; Vávra, Vladimír ; Franc, J. ; Fronc, Václav ; Fronc, Václav
The single crystals of TGS doped with Pt-ions and with L-alanine were grown as in ferroelectric phase as the full-shaped crystals. The growth rate along the axis c of the doped crystals is much higher than in an undoped one. Morphology, domain structure and hysteresis loops were investgated. The effect of the dopant on the growth velocity is explained on the basis of catalytic action of platinum complexes. The pyroelectric detectors were prepared from these materials and their parameters are presented.
2003 Program of Development in Metrology. Progress Report on Project M/19/03: Primary metrology of time and frequency
Čermák, Jan ; Buzek, Otokar ; Čemusová, Blanka ; Šojdr, Ludvík
The report brings a summary of the results obtained by The Institute of Radio Engineering and Electronics (IREE) in the field of primary time and frequency metrology realizing the M19/03 project of The Metrology Programme of the Czech Office for Standards, Metrology and Testing in the first half of 2003.
