ABSTRACT:
An apparatus for determining flight parameters of a ball in flight along a flight path, includes a pair of light conditioning elements on the ball, a first set of sensors having mutually orthogonal fields of view intersecting along a first plane through which the ball initially passes during flight and a second set of sensors having mutually orthogonal fields of view intersecting along a second plane through which the ball subsequently passes during flight. Each sensor includes a linear array of photodiodes for obtaining a linear image of a linear section of the ball. A controller successively pulses the sensors at microsecond intervals to obtain multiple, successive linear images of successive linear sections of the ball to obtain first and second reconstructed images of the entire ball and the locations of the elements thereon at the first and second planes, respectively, and processes changes in the locations of the elements at the first and second planes to derive the flight parameters.
