A swing analysis system includes a housing having an upper surface and a ball support mounted to the upper surface. A first array of optical sensors is mounted in the upper surface on a first side of the ball support, and a second array of optical sensors is mounted in the upper surface on a second side of the ball support, opposite the first array of sensors. A third array of optical sensors in mounted in the upper surface, with the sensors positioned around the ball support. A controller is coupled to each sensor of the three arrays of sensors for receiving output signals therefrom. The controller monitors the output signals for change in state events and creates data files containing a sequence of events with associated timestamps. The computer is programmed to use the data files to calculate swing path angle, club head speed, club head angle, club head lateral alignment with respect to the ball support, and club head height of an implement (e.g., a golf club) swung over the housing. The system can also be provided with at least one tower attached to a side of the housing and extending above the upper surface. The tower includes additional sensors that are used by the computer to calculate club head loft angle. The computer can also calculate an effective club head speed from the measured values of club head speed, swing path angle, club head lateral alignment and club head angle.
