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

FIELD: optical systems of guided missile guidance systems, applicable in weapons control systems with teleorientation in the laser beam.

SUBSTANCE: the optical sight of the guided missile guidance system has an aligned sight and a searchlight including two injection lasers, whose radiating areas are located perpendicularly to the axes of the measured coordinates, radiation output system of the lasers to a single optical axis, an optical scanner in the form of a rotating prism and a pancreatic objective successively installed on this axis, the prism axis of rotation is matched with the objective optical axis, as well as a an opaque shutter installed on the mount of the rotating prism, two optron sensors fixed in parallel with one of the measured coordinates. In the plane perpendicular to the optical axis of the searchlight, the angle between the line connecting each sensor with the axis of rotation of the prism makes up 90 deg, the outputs of the first and second optron sensors are connected respectively to the inputs of the first and second delay circuits, whose outputs are connected respectively to the first and second inputs of the pulse shaper. Introduced are the temperature-sensitive element, first and second voltage switches, the first control inputs of the first and second voltage switches are connected respectively to the first and second outputs of the pulse shaper, and the second inputs - respectively to the outputs of the first and second controlled voltage sources, whose control inputs are connected to the output of the temperature - sensitive element, and the outputs of the first and second voltage switches are connected respectively to the inputs of the first and second lasers.

EFFECT: enhanced reliability of sight operation due to stabilized power of lasers within the whole range operating temperatures.
