PULSE IMAGE CONVERTER Russian patent published in 2014 - IPC H01J31/50 

FIELD: electricity.

SUBSTANCE: invention relates to electric engineering. A pulse image converter comprises a key block, including the first voltage converter 1, the first microcontroller 2, the second voltage converter 3, a pulse generator 4; a power supply unit, including the second microcontroller 5, an analogue-to-digital converter 6, the first and second digital-to-analogue converters 7 and 8, an amplifier 9, a microchannel plate amplifier 10, a display amplifier 11, a microchannel plate multiplier 12, a display multiplier 13, a photocathode multiplier 14; an evacuation unit, including a display 15, a microchannel plate 16 and a photocathode 17. The second voltage converter 3 provides high voltage for the pulse generator 4. While operating in a continuous mode the second voltage converter 3 is switched off thus saving energy of the external power supply unit. At that constant voltage of the photocathode is generated by means of the photocathode multiplier 14. The microchannel plate multiplier 12 generates high voltage for the pulse generator 4, which ensures active blockage of the photocathode gap while operating in the pulse mode.

EFFECT: improvement of resolution using image converters of the third generation in a wide range of illumination and reduction of consumed power.
