OPTIC TARGET SENSOR Russian patent published in 2013 - IPC F42C13/02 

FIELD: weapons and ammunition.

SUBSTANCE: optic target sensor includes two and more receiving-emitting channels, each of which includes an electronic unit, an optic emission pulse source and a photoreceiver, which are connected to the electronic unit. Optic axes of the optic emission pulse source and the photoreceiver, which form a receiving-emitting channel, are directed at an angle of ≤90° to ammunition longitudinal axis in the movement direction and located with an offset relative to each other. Receiving-emitting channels are arranged about ammunition longitudinal axis. An angle between emitters of adjacent receiving-emitting channels in radial direction is chosen so that light beams of emitters do not intersect between each other; with that, distance between beams of neighbouring emitting channels at the required distance of the target detection is equal to/approximately equal to minimum size of the target.

EFFECT: improving probability of detection of small-size targets; providing high accuracy of installation of the specified actuation range; enhancing protection against optic and small-size interference, and reducing weight-and-dimensional characteristics.
