Control system for the furmance Heat Flux is described
The control system for the furnace Heat Flux is used for the temperature control of two volumes furnace and for the measuring of temperature difference between this two volume
Control system for fluorescence optical laboratory in the Institute of Radioengineering and Electronics
The goal of control system of the optical laboratory for luminescence is designed for controlling of all optical electronical and mechanical components of luminescence spectrometer like cryostat, laser, monochromator and data sampling from this physical experiment
Control system for laser topograph
The goal of the laser-topograph control systems is the measured sample positions control in the perpendicular plane to the direction of the laser beam and data sampling from lock-in-amplifier. The lock-in-amplifier is detecting the secondary luminescence light from the measured sample
Computer control of photoluminescence spectrometer used for characterization of semiconductors
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 sectrometer Oriel
The PC control unit for measurement of optical spectra through spectrometer Oriel is described. The analog data from optical detectors are converted to digital form and stored in HDD of PC machine
The camera vizualization system of precision mesuring situation for semiconductor tester
The CCD camera vizualization system is used for precision position setting of testing needle for topografical I/U measuring characteristic
Control system for Eurotherm controller
Software for measuring secondary luminiscation is described. Software can switch power grades of heating and can gain actual temperature from Eurotherm controller
Control system of the electronic shutter
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
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
