Abstract
An apparatus and method for quantifying the stiffness of a golf ball or golf ball core under normal use conditions while also measuring the contact time, wherein an air cannon, or the like, is used to shoot an object horizontally against a block while the inbound and outbound velocities of the object are measured by two light gates separated by a given distance and the contact time is measured by optical sensors located at the block, and wherein the measured times and calculated velocities are then used to calculate the coefficient of restitution and contact time of the object.
