1. A golf club swing measurement apparatus, said apparatus comprising: at least two parallel planar displacement sensors including a first planar displacement sensor having a longitudinal axis aligned parallel to and on a first side of the axis of an intended golf swing, and a second planar displacement sensor having a longitudinal axis aligned parallel to and on a second side of the axis of an intended golf swing, said first and second planar displacement sensors each having a length and an output proportional to the position of a golf club head along said length; a detector connected to said at least two parallel planar displacement sensors; and a processor connected to said detector for processing signals from said detector to continuously calculate the swing parameters of a golf club head moved over said at least two parallel planar displacement sensors.
