OPTICAL SIGHT FOR FIREARMS Russian patent published in 2009 - IPC F41G1/00 

FIELD: weapons and ammunition.

SUBSTANCE: invention relates to optical instrument making and can be used in optical sight of firearms and fowling pieces. The proposed optical sight comprises a lens, lens ring, assembly to form target reticule and device to match the sight-leaf hairline with the gun barrel axis. The target reticule formation assembly represents a liquid-crystal matrix, while the device to match the sight-leaf hairline with the gun barrel axis represents a control circuit allowing the selection of the target reticule configuration and control of the displacement of target reticule image over the liquid-crystal matrix field. The latter device comprises aforesaid target reticule formation assembly, microcontroller, power supply and switch. The liquid-crystal matrix is arranged in the lens or lens ring focal plane.

EFFECT: higher accuracy of fire, simplified sight coincidence adjustment and reduced time of ranging.
