METHOD FOR MEASUREMENT OF FIRE ARMS BARREL BENT AND DEVICE FOR ITS IMPLEMENTATION

摘要

The invention relates to area of fire arms and can be used for increase of accuracy of shooting. Method for registration of barrel of fire arms bent is in fact that optical radiation of point source installed near the base of the barrel reflected from flat mirror installed on barrel end is directed through objective and rotary optical wedge to four-site photo-receiver and bent of barrel is determined through ratio of durations of photo-receiver sites illumination. Device for realization of method includes source of optical radiation, mirror and receiver of optical radiation. Between the mirror and the receiver of optical radiation objective and rotary optical wedge are installed. The invention makes it possible to increase accuracy of measurement.
