摘要：A golf green measuring device according to the present invention includes aplurality of spaced apart rails attached to an enclosed structure. The structure includes acontrol unit including a microcontroller, circuitry, a battery, a display and a level indicator.
The rails include infrared emitters and detectors that sense a golf ball traveling throughthe enclosed structure. The microcontroller measures the elapsed time the golf balltravels between a pair of detectors disposed at the rail front end and the elapsed timethe golf ball travels between another pair of detectors disposed at the rail rear end. Thechange in velocity or deceleration of the golf ball is determined based on the measuredtime intervals and converted into a speed value. The computed speed value is displayedon a device display. The device may include an optional printer to provide a hardcopy ofthe measurement.
