ABSTRACT:
Apparatus for determining how squarely a golf club face is presented to the ball near and at the point at which the club face makes contact with the ball. Collimated light from outside the clubhead arc on the target line-of-flight strikes a reflective patch fixed to the club face. The reflected beam is picked up by sensors, each of which if struck by light switches on an adjacent marker light. Thus the path followed by the reflected beam during one stroke is marked in lights for study or playback. As few as one or as many as thousands of sensors may be used, with suitable adjustment to the optics. If the marker lights turned on are right or left of target it indicates a non-square blow. Information about clubface loft angle during the stroke is obtained from the starting and stopping point of the line of marker lights. Opening or closing the clubface near the contact point results in the line of marker lights being other than vertical. SCRs are used to turn on the marker lights so each one stays on until reset. Results may be stored and played back in more elaborate versions, but the preferred embodiment merely displays.
