Device to measure the motion of a golf club
A club shaft that can be installed in a club head permanently or can be installed in clubs with interchangeable shaft features is disclosed herein. The invention is a measurement system that enables the capturing of the speed and motion of the golfer's swing. The invention uses infrared reflectors positioned on a golf club and an array of infrared sensors.
1. A system for measuring the motion of a golf club swung by a golfer, the system comprising:
a golf club comprising a shaft and a golf club head, the golf club having a plurality of infrared reflectors thereon;
a golf ball positioned on a tee extending upward from a mat;
a plurality of infrared sensors positioned to create a swing field for reception of a reflected signal from the plurality of infrared reflectors as the golf club is swung through the swing field, each of the plurality of infrared sensors generating infrared radiation;
wherein the plurality of infrared sensors is able to capture the speed and motion of the golf club as the golf club is swung through the swing field by a golfer; and—herein the plurality of infrared reflectors comprises a first infrared reflector on a toe-end position of the golf club head, a second infrared reflector on a lower portion of the shaft and a third infrared reflector on an upper portion of the shaft.
2. The system according to claim 1 wherein each of the plurality of infrared sensors comprises a LED that generates infrared radiation and a photodiode for receiving the reflected infrared radiation from the plurality of infrared reflectors.
