SIGHTING DEVICE Russian patent published in 1997 - IPC

FIELD: military equipment, in particular, sighting equipment of weapon complexes of fighting vehicles. SUBSTANCE: sighting device uses series-connected sighting mark brightness variation unit 6, whose first input is connected to the output of power source 3, and the second input - to the third output of layer's control panel 18, adder 9 and low-pass filter 8, whose output is connected to the second input of sighting mark lighting unit 7, series-connected periodic signal generator 4, whose input is connected to the fourth output of the layer's control panel, periodic signal frequency control unit 1, whose second input is connected to the fifth output of the layer's control panel, and the second output - to the second input is connected to the fifth output of the layer's control panel, and the second output - to the second input of low-pass filter 8, periodic signal amplitude control unit 2, whose second input is connected to the sixth output of the layer's control panel, and the third input - to the second output of sighting mark brightness variation unit 6, limiting unit 5, whose second input is connected to the seventh output of the layer's control panel, and the output - to the second input of adder 9. Provision is also made for light filter unit 10, whose input is optically integrated with the output of sighting mark lighting unit 7, and the output - with the second input of sighting mark formation unit 12, target range unit 19, whose input is connected to the eight output of the layer's control panel, and series-connected delay unit 16, whose input is connected to the ninth output of layer's control panel 18, drive 17, whose second input is connected to the output of target range unit 19, and aperture diaphragm 13 that is optically integrated through its second input with the output of optical forming system 14, and through the output - with the first input of sighting mark formation unit 12. EFFECT: improved design. 1 dwg
