Abstract:
A golf swing analysis system useful in determining movement of a golf club head during the execution of a golf swing by a player, the system comprising:a radiation source for providing a plane of radiation through which radiation plane the golf club can pass; a plurality of radiation sensors dimensioned for carrying by a golf club, the radiation sensors responsive to an orientation of a ball striking face of a golf club head, the radiation sensors providing a radiation sensing signal responsive to first and second portions of the golf club head passing through the plane of radiation, wherein the radiation sensor comprises a radiation receiver having a plurality of radiation sensors orthogonally arranged at measurable preselected locations with at least three of the plurality of radiation sensors defining a radiation sensor plane, the radiation sensor plane representative of the striking face of the club head; timing means operable with the radiation sensor for receiving the radiation sensing signal and for determining a time period between passage of the first and second portions of the head through the radiation plane; and processing means for processing the time period and calculating a characteristic value for club head movement through a ball impact zone.
