DEVICE FOR DETERMINATION OF CLOSE PATTERN Russian patent published in 1997 - IPC

FIELD: test of ammunition in target range, in particular, in tests of rifle cartridges at shooting at a multi-lobe target. SUBSTANCE: the position of the projected wounding element is determined according to the position of the wounding element shady spot on the transparent coating of the target at the instant of flying-up of the wounding element to the target. The device uses a target that is indestructible by the wounding elements of the weapon under test, optoelectronic detector optically integrated with the target, storage unit, synchronizer, display device; the optoelectronic detector has an analog-to-digital converter unit, the optoelectronic detector is positioned at an angle to the target plane and made in the form of optically integrated objective lens and fiber-optic image analyzer, whose inlet ends are geometrically similar to the target, and the outlet ends are conjugate to the linear photodetector cell unit, whose outputs are connected to the inputs of the storage unit connected via the analog-to-digital converter unit to the inputs of the display device; the synchronizer output is connected to the additional input of the storage unit. The target may be made if citall. EFFECT: enhanced accuracy. 2 cl, 1 dwg
