Patent abstract
A method and system for monitoring a fleet-angle of a cable. An embodiment may monitor the fleet-angle of a cable being spooled or unspooled in multiple radial directions and without use of a mechanical monitoring apparatus. The method and system may employ a fleet angle sensor device having a bell-shaped aperture across which propagate one or more collimated light beams that may be used to detect excessive fleet-angle of the cable. The light beams may be generated by a fleet-angle sensor disposed in the fleet angle sensor device proximate to the aperture. Various light-beam patterns within the aperture may provide different advantages when determining deviations of the cable from the aperture center axis.
