FIELD: physics, optics.
SUBSTANCE: invention relates to electrooptical instrument-making. The device comprises a lens antenna which receives and focuses electromagnetic radiation, an evacuated dielectric housing, an electronic processing unit and an image display connected to said processing unit. The housing has a screen configured to operate as a secondary electron collector. The device further includes an electron supply unit, intended for generating a modulated pulse, and a sensitive element which receives the modulated pulse and focused rendered electromagnetic radiation. A set of decomposition elements representing capacitors having first and second plates separated by a dielectric spacer, wherein the first plate of the capacitors from the set is located on the side of incident rendered electromagnetic radiation and functions as an antenna, which absorbs the focused rendered electromagnetic radiation, which modulates the modulated pulse, and the second plate of the capacitor is located on the opposite side of the dielectric spacer and has electrical connection with the electronic processing unit to transmit the generated resultant modulated signal to said processing unit. The sensitive element is configured to convert the incident rendered electromagnetic radiation into alternating electric charges with resonance frequency determined by the geometric dimensions and shape of the decomposition element.
EFFECT: high sensitivity and resolution, easy adjustment and operation.
