Bullet impact detection device for determining the position of impact of a bullet on a target comprises two laser scanning arrangements for detecting the bullet-target entrance point from two positions

摘要

Device for determining the impact position of a bullet in a planar target representation. The device comprises an optical arrangement with a beam deflection module (3, 4) that is used to linearly scan the measurement plan with a rotating beam in order to detect a bullet in the measurement plane. Light reflected from the bullet is detected and together with its time of detection is used to determine the impact position of the bullet by trigonometry. Independent claims are made for two further devices for determining the position of impact of a bullet relative to a planar target.
