Abstract
The present invention relates to a golf training device capable of forming a two-dimensional, single planar and total symmetrical optical sensor net for detecting movement of a golf ball. The device comprises a square frame which has a signal producing means holding part on the first horizontal and the first vertical sides of the frame and a signal detecting means holding part on the second horizontal and the second vertical sides of the frame. On the signal producing means holding part, a light signal producing means including a light signal emitting means is installed to generate a two-dimensional, single planar optical path net. A light signal detecting means is spatially arranged in the opposite sides of the frame in accordance with the light emitting means to form a totally symmetrical optical sensor net for detecting the light signals from the light signal producing means. The present invention also includes a golf ball sensor means for detection of the golf ball movement at its initial impact and a data processing and display means which receives and processes output signals from the light signal detecting means for calculating the golf ball's take-off speed, the horizontal …
