Abstract
A technique for measuring golf swing tempo or clubhead speed for a golfer swinging a golf club through a tee area. Two parallel infrared (IR) transmitters transmit respective IR beams along predetermined lines toward the tee area. Respective IR sensors receive respective IR beams reflected from a reflector mounted to the shaft of the golf club, near the clubhead. Each IR sensors provides a respective output signal indicative of the passage of the golf club through a corresponding IR beam. Predetermined sequences of output signals from the IR sensors are detected and the differences in time between various output signals are measured to provide tempo and clubhead speed values for display on a LCD screen. The speed values can be compensated values as obtained from look-up tables.
