OPTOELECTRONIC SYSTEM FOR AIR DEFENCE MISSILE SYSTEM Russian patent published in 2011 - IPC F42B15/01 F41G7/22 

FIELD: physics.

SUBSTANCE: optoelectronic system for an air defence missile system has an pointing head (5) mounted on a precision two-coordinate turning device (8), as well as a computing unit (13), a monitor (15) and a control unit (16). The pointing head (5) has a double-channel design with wide (6) and narrow (7) field of vision television channels. The optoelectronic system is fitted with a unit for superimposing wide and narrow field of vision images (14). The lens of the narrow field of vision channel has a mirror-lens design with central screening and includes a main concave mirror (19) and a convergent mirror (20) arranged in series, as well as annular first (21) and second (22) optical wedges placed in front of the convergent mirror (20) with possibility of independent rotation relative each other around the optical axis of the lens. The outer diameter of the optical wedges is equal to the diameter of the main concave mirror (19), and the inner diameter is equal to the diameter of the convergent mirror (20). The wide field of vision (6) channel is placed in front of the narrow field of vision (7) channel having a common optical axis with it. The diameter of each of the components wide field of vision (6) channel does not exceed the diameter of the convergent mirror (20).

EFFECT: possibility of battery launch of a missile with one air defence missile system at several targets at once.
