Abstract: 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.

Abstract: An optical sensor net system for measuring the relational dynamic information of a spheroidal projectile. A support frame for the system may include light emitters that generate divergent non-parallel rays of light. The non-parallel rays of light emitted may be directed to and received by a plurality of light detectors substantially arranged within a single plane. The intersecting non-parallel rays of light may form an asymmetrical optical sensor net that may also capture both golf ball and golf club information as they pass through. The light detectors that receive the rays of light may be spaced apart at preselected locations and distances less than the diameter of a spheroidal object such as a golf ball.
