Abstract
A putter alignment system (10) is provided for use in aiding in practicing golf putting. The system (10) includes a putter component (12) mounted on a golf putter (12) and a remote target component (14) situated along the desired relative alignment axis (18) from the putter (20). Electronic components are utilized to determine relative alignment of the putter (20) to the target by analyzing an reflected slot beam (16). The preferred embodiment includes an emitter (68) on the remote target component (14) and a cylindrical subsection reflector (50) of one of several acceptable configurations on the putter component (12) to created and delimit the beam (16). The reflector (50) is mounted on the putter (20) so as to be perpendicular to the putter axis (49) such that on perfect alignment a the slot beam (16) will coincide with the alignment axis (18). The horizontal position of the slot beam (16) is detected by an array of photosensors (69 ) while signal output is provided by signal lights (75) corresponding to the relative alignment. Electronic signal analysis components in the receiver/sensor assembly (32) provide improved resolution and performance by utilizing synchronous demodulation and multiple operational loops for channel signal analysis. Alternate signal outputs allow analysis of a putting stroke as well as of static prealignment.
