OPTICAL SIGHT FOR GUIDANCE SYSTEM OF GUIDED MISSILE Russian patent published in 2005 - IPC

FIELD: weapons.

SUBSTANCE: optical sight comprises axially aligned sight and light source that is made of two injection lasers whose emitting zones are perpendicular to the axes of co-ordinates to be measured, system for adjusting the laser beams to single optical axis, and scanner made of rotating prism and objective lens mounted at the optical axis in series. The axis of rotation of the prism is in coincident with the optical axis of the objective lens. The nontransparent shield is mounted on the mandrel of the rotating prism. Two optronic pickups are immovably mounted parallel to the coordinate to be measured. In the plane perpendicular to the optical axis of the light source, the angle between the lines that connect pickups with the axis of rotation of the prism is 90º. The outputs of the first and second optronic pickups are connected, respectively, with the inputs of the first and second delay circuit whose outputs are connected, respectively, to the first and second inputs of the OR circuit and first and second inputs of the permanent memory. The output of the OR circuit is connected with the first inputs of the timer and channel commutator. The output of the timer is connected with the third input of the permanent memory whose second input is connected with the output of the reference generator and second input of the timer. The output of the code-time converter is connected with the second input of the channel commutator whose outputs are connected, respectively, to the inputs of the first and second lasers. The sight is provided with the counter of scanning cycles whose output is connected with the forth input of the permanent memory. The counting input is connected with the output of the second dely circuit.

EFFECT: enhanced precision of sighting.
