    Features of execution of the converter pressure in scanning a television optical microscope
    (Видавництво Львівської політехніки, 2012) Vasiliuk, Vladimir; Dorozhivska, Marta; Liubinetska, Bogdana; Shkliarskiy, Volodimir
    Ways of design of precision voltage-current converters (VCC) are proposed. VCCs are used for formation of currents in deflection coils with high accuracy and stability. Currents form scanning raster on high resolution ELT screen.

    Scanning television optical microscope for research of biological microobjects
    (Видавництво Львівської політехніки, 2010) Balanjuk, Yurij; Lubinecka, Bogdana; Matiieshyn, Yurij; Pedan, Anatoliy; Prudyus, Ivan; Turkinov, Gennadiy; Shkliarskyi, Volodymyr
    Ways of construction of a scanning television microscope which can be used for research of biological microobjects are analyzed. Opportunities of a microscope are expanded due to formation of a raster in television and little-frame mode. Ways of change of the size of a raster are offered at preservation of the resolution of the image of microobject.

    Correcting of non-uniformity of brightness of the image in a scanning microscope
    (Видавництво Львівської політехніки, 2010) Balanjuk, Yurij; Goj, Vitaliy; Turkinov, Gennadiy; Shkliarskyi, Volodymyr
    The reasons of occurrence of non-uniformity of brightness of formation of the image of researched microobject in the scanning television optical channel are analyzed. Ways of removal of components of nonuniformity of a signal are specified.

    Raster forming block in scanning television microscope
    (Видавництво Львівської політехніки, 2010) Vasylyuk, Volodymyr; Goy, Vitaliy; Shkliarskyi, Volodymyr
    The ways of construction of raster forming block, which provides television and little-frame modes, are considered. The analog and digital methods of formation of signals are analyzed. Ways of change of amplitude and displacement of signals of a raster are shown with the purpose of maintenance of scaling of the image of researched microobject.
