20140024470 | GOLF ANALYSIS SYSTEM WITH FRAMELESS OPTICAL SENSOR NET - A golf analysis system includes a light emitter assembly, including first and second light emitters spaced apart from one another, and a light detector assembly, including first and second sets of light detectors arranged along a surface of a practice area beneath the light emitters. The light emitters emit first and second spreads of non-parallel light rays, received by the light detectors, to form an optical sensor net for capturing relational kinetic information when at least one of a golf ball and a golf club passing through the optical sensor net. The region between the level of the light detectors and the level of the light emitters is substantially free of mechanical structure. | 01-23-2014 |
