ELECTRO-OPTICAL CONVERTER AND METHOD OF PRODUCING VIDEO Russian patent published in 2014 - IPC H01J31/56 

FIELD: physics, optics.

SUBSTANCE: invention relates to electronic engineering and more specifically to electro-optical converters. An electro-optical converter, configured to filter visible light in three selected wavelength ranges of red, green and blue colours (R, G, B), comprises a housing which is divided into an evacuated and a non-evacuated part with an input window which is in form of a fibre-optic plate, on the output surface of which there is a photocathode, and an output window, an electron-excited black and white CCD array placed inside the housing and whose back side faces the input window and insulated from optical radiation at the front side, an electron focusing system placed between the photocathode and the black and white electron-excited CCD array, a primary video signal generating unit, a video signal processing unit, a control panel and a visible image reproducing device in form of a microdisplay mounted in the output window of the housing. The input surface of the electro-optical converter has areas configured to filter visible red, green and blue light, and areas that are not configured to filter optical radiation, wherein areas configured to filter visible light are uniformly distributed on the input surface of the electro-optical converter among areas not configured to filter optical radiation.

EFFECT: high sensitivity of the electro-optical converter in low-illumination conditions.
