SIGHTING DEVICE Russian patent published in 2006 - IPC F41G3/00 

FIELD: devices for sighting of various objects, for example, targets at firing.

SUBSTANCE: the device has an operator's control panel, optical forming system, first and second control units, screening unit, series-connected power supply source, brightness varying unit, adder, low-frequency filter, sighting index illumination unit, light filter unit and a sighting index forming unit, as well as a periodic signal generator with their adjustment unit, transducers and amplitude and frequency indicators. The device uses also an additional index forming unit, ammunition type transducer, transducer of ammunition initial distance from the target and a transducer of variation of this distance at movement of the carrier all connected to the first, second and third inputs respectively, index illumination frequency mismatch indicator, unit for input of images to the field of vision of the sighter-operator, whose first input is connected to the output of the additional index forming unit, and the second input-to the output of the index mismatch indicator. The introduced elements and couplings provide for expansion of the device functional potentialities, in particular, enhancing of the sighting accuracy, which makes it possible to enhance the device efficiency by 15 to 17%, and timely take the respective measures for correction of the characteristics both of the device and operators. Besides, opportunities are enhanced in estimation of the influence of various environmental conduits on the efficiency of operations of the sighting device and operators.

EFFECT: predicted variations of indications of the functional activity of the operator.
