Apparatus and Method for Determining the Spatial Position and Velocity Vector of a Spherical Projectile

摘要

A spherical projectile is detected as it passes through an array of planer light beams and associated detectors. The construction of the Apparatus is such that at least 4 planar light beams are obscured by the passing projectile, two parallel beams in one direction and two parallel beams in a second direction. The apparatus records the time at which each affected light beam is obstructed by the passing projectile, The Apparatus than calculates both the spatial position and the 3 dimensional velocity vector of the projectile.
