PYROELECTRIC ELECTRON-OPTICAL IMAGE INTENSIFIER Russian patent published in 2008 - IPC H01J31/52 

FIELD: electricity.

SUBSTANCE: invention is related to the sphere of radio engineering, namely: to electron-optical instruments, which transform thermal images of different objects in the middle and distant infra-red ranges. Device contains the source of uniform electron flow, which is a photocathode solid-made of material that is transparent for infra-red radiation, pyroelectric target with through openings. Layers of pyroelectric layer are located on the conducting layer between the through openings. Technical result is achieved because there are additional through openings made in pyroelectric target in the area of absorbing layer discrete elements, and the size of all through openings is made less than the length of detected radiation wave, and the width of additional through openings, which are located in the area of absorbing layer discrete elements, is made, wherever possible, equal to the width of bridges between these openings, and also equal to the width of slit-like through openings that separate discrete elements of absorbing layer.

EFFECT: increases sensitivity and resolving power of instrument by configuration change.
