DEVICE TO MEASURE BEND OF ARTILLERY BARREL Russian patent published in 2012 - IPC G01B11/24 F41G3/32 

FIELD: weapons and ammunition.

SUBSTANCE: device to measure bend of an artillery barrel includes an angled three-edged reflector 9, a reflector lens 1, designed for location on the barrel end 2, and a metering unit 3 optically coupled with them, comprising a lens 7 and a photodetector 8, forming a receiving channel, and also an optical mark 5, installed between a radiator 4 and a beam splitter 6. The radiator 4 and the optical mark 5 form a light beam shaper. The beam splitter 6 couples optical axes of the light beam shaper and the receiving channel. A system 10 to generate images of an optical mark may be introduced into the composition of the metering unit 3. The reflector lens and the angled three-edged reflector may be arranged in the form of a single monoblock part from transparent material, on the output face of which there is a spherical surface.

EFFECT: higher accuracy of measurement under complicated operational conditions.
