Abstract
A spherical object 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 object, 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 object. The apparatus then calculates the spatial position, velocity and trajectory of the object.
