SIGHT-GUIDANCE INSTRUMENT Russian patent published in 2007 - IPC F41G11/00 

FIELD: optical instrument engineering, in particular, devices for aiming and guidance of guided projectiles.

SUBSTANCE: the sight-guidance instrument has two parallel channels. The first channel (sighting) has an optically communicated objective lens, optical conjugation system, and an observation system with a sight mark. The second channel (guidance) has successively positioned and optically communicated laser radiator, raster modulator with a built-in system of lighting of its operating zone by visible radiation, pancreatic system, collecting lens, spectrodivider and an objective lens. The sight-guidance instrument has also a device for monitoring of the parallelism of the guidance channel and sighting channel axes made in the form of an afocal cat's eye and installed before the objective lens in its optical axis for extraction of the sighting channel and adjusting channel transpositions from the ray path in two mutually orthogonal directions that are perpendicular to the optical axis of the objective lens. The collecting lens is installed in the focal plane of the objective lens for the light wave length corresponding to the radiation of the laser radiator for adjusting transpositions in two mutually orthogonal directions that are perpendicular to the optical axis of the objective lens.

EFFECT: enhanced accuracy of guidance of guided projectiles, reduced overall dimensions of the objective lens and of the sight-guidance instrument upon the whole, as well as simplified construction of it.
