Mikropočítačový řídící systém pro výrobu optických tyčí a trubic
Kostka, František
A control system for the production of optical tubes and rods was developed in the IREE AS CR, as a continuation of prior effort to control drawing process of optical fibres. The latter system was modified; in particular in the power driving unit a newly constructed pulling device was added, enabling, with the help of an array of pulleys and a town belt, the drawing of optical tubes and rods.
Computer control of photoluminescence spectrometer used for characterization of semiconductors
Kostka, František ; Zavadil, Jiří ; Krechler, Jindřich ; Dvořák, Martin ; Svatuška, Michal ; Gladkov, Petar
Basic electronics and programming that enables a computer control of experimental set-up for low-temperature photoluminescence /PL/ spectroscopy and PL topography is briefly described together with the physical principles behind photoluminescence spectroscopy as a characterization technique.
Control system of the electronic shutter
Kostka, František
Application of the electronic shutters lies, in addition to the electronic cameras, mainly in the field of photonics, photometry, holography, and by their exposition of photographic materials in optical laboratories. The contribution delas with the principles of control of the electronic shutter and with the construction of the control systems.
Application of programmable logical fields by the construction of microcomputer
Kostka, František
The contribution deals with the microcomputer signals modification by programmable logical field. In one regime, the microcomputer operates in the standard mode, reading instructions from the program's external memory; the second regime is programming, whereby it selfprogrammes its own program memory from a file stored in the PCMCIA memory card.
