Electro-optical projectile analyzer

摘要

A device for determining the velocity, trajectory and attitude of a projectile. Light beams from two perpendicular linear arrays of light emitters are incident upon corresponding linear photodetector arrays. Each light beam in the linear arrays includes an individualized characteristic to permit unique identification of each beam. Trajectory and velocity parameters are determined by identifying which detectors have an interrupted light beam and from the time interval between actuation of the arrays.
