METHOD TO VISUALISE ELECTROMAGNETIC RADIATIONS AND DEVICE FOR ITS REALISATION Russian patent published in 2014 - IPC G01T1/28 

FIELD: instrument making.

SUBSTANCE: method to visualise electromagnetic radiation with high resolving capacity, and also a small-sized device for its realisation. The device comprises a lens antenna receiving and focusing electromagnetic radiation; a vacuumised dielectric body with a screen that contains a window letting through radiation and holds a sensitive element arranged in the focal plane of the lens antenna and an electronic-optical converter; an electronic unit of processing and a device of image reproduction, besides, the sensitive element comprises a metal substrate-base electrically connected to the screen of the vacuumised dielectric body, with the dielectric gasket at the side of falling radiation, with a set of decomposition elements on it, which are made as capable of absorbing focused electromagnetic radiation and converting it into alternating electric charges with frequency set by geometric dimensions of the decomposition element, besides, each decomposition element from the set of decomposition elements has a capacitance link with a metal substrate-base, besides, the electronic-optical converter, to ensure emission of previously excited electrons, is made as capable of creating an external static field with energy equal to: EA=Ev mat - Ev0 - Eemr, where Ev mat - energy of material electrons release, Ev0 - rest energy of an electron, Eemr - alternating energy of a charge generated on the lining of the decomposition element when receiving absorbed visualised electromagnetic radiation, EA - energy of external homogeneous static electric field, besides, the electronic-optical converter comprises an element of conversion of an information flow of electrons, besides, each of the decomposition elements is made of material having high field emission at low value of electric field intensity.

EFFECT: higher quality of an image due to increased resolving capacity and reduced noise, higher sensitivity, reduced mass and dimensions, reduced power consumption.
