Golf club swing analyzers

A golf club swing analyzer comprising:

• a housing;
• a light emission device configured to emit reference light in a substantially vertical direction toward a location in the path of a golf club swung adjacent the housing, the light emission device being further configured to emit the reference light in a plurality of pulses individually having a duration less than the duration of one of the rise time and fall time resulting from the swung golf club blocking incidental light from the light reception device;
• a light reception device supported by the housing and configured to receive reference light emitted from the light emission device and reflected from the swung golf club;
• and
• discrimination circuitry coupled with the light reception device and configured to distinguish the reflected reference light received from the light emission device from incidental light by generating a timed pulse responsive to reference light being received within the light reception device, the timed pulse having a duration greater than the duration of the reference light pulses and less than an individual one of the rise time and fall time.

A golf swing analysis method comprising:

• emitting reference light toward a location in the path of a golf club swung adjacent the housing;
• receiving reference light reflected from the swung golf club;
• receiving incidental light;
• discriminating the reflected reference light and the incidental light following the receivings;
• and
• generating at least one indication signal responsive to the discriminating.
