OPTICAL UNIT Russian patent published in 2013 - IPC F42C13/02 

FIELD: weapons and ammunition.

SUBSTANCE: optical unit comprises electronic unit and transceiving channels including optical radiation source and photo receiver with their optical axes directed at <90° to round lengthwise axis and shifted relative to each other, preferably, in parallel, or in fact in parallel. Note here that said transceiving channels are arranged along round lengthwise axis, mainly in the plane perpendicular to its lengthwise axis to form the angle in radial direction between axes of radiators at adjacent transceiving channels. This angle makes light beams of radiators not intersecting and spacing between beams of adjacent radiating channels equal or approximate to minimum size of slot. Optical radiator and photo receiver are connected with electronic unit to perform time-pulse analysis of range to target.

EFFECT: higher probability of target detection and guidance, better protection against optical and small size interferences, decreased weight and overall dimensions.
