ABSTRACT:
A striking instrument and struck object monitoring system including at least two shutterable camera units which view a field of view each of which cameras receives light patterns from each and every one of a plurality of contrasting areas on the instrument and the object in rapid successive sequence. A computer receives the signals generated by the light patterns as received by each camera unit which computer discriminates between such signals to determine the instrument's movement and orientation, and the conditions at impact with the object.
The striking instrument may be any selected golf club which club is initially scanned by the system to determine it's proper striking location prior to the club being swung through the field of view.
