    No full text
    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

    No full text
    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

    Control system of the electronic shutter

    No full text
    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

    No full text
    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
