OBJECT SIGHTING DEVICE Russian patent published in 2008 - IPC G02B23/12 G03B9/42 

FIELD: instrument making.

SUBSTANCE: invention relates to concerns to optronics devices, in particular, to devices of recognition of objects. The object sighting device includes a lens for formation of the object image arranged on optical axis, a photo shutter arranged in a converging bunch of beams and provided with a drive connected to electronic unit generating a signal for the shutter to operate and photoreception unit with the data processing unit. Here, the photo shutter represents two parallel plates arranged to move along the line of dispersion towards each other and normal to optical axis, each of which being furnished with slots forming diffraction grating made along the branches of family of hyperboles.

EFFECT: higher of protection of optical system from blinding, higher recognition of distant objects, smaller sizes.
