Laser-controlled plane control system for golf swing, has multiple laser units generating controllable laser plane, where signaling is carried out during penetration of laser plane with club head

摘要

The system has multiple laser units provided with a cone laser and a rotating laser and generating a controllable laser plane. A golf club is provided with a laser sensor, which generates signals e.g. acoustic signal and vibration signal, during penetration of the laser plane with a club head. The acoustic signal is provided with different tone pitches, and the vibration signal in a racquet handle exhibits different frequencies. Signaling is carried out during penetration of the laser plane with the club head.
