A slip ring is a rotary electrical interface, collector, swivel or joint. It is a component
or architecture that can perform continuous data transfer between a rotary and
stationary structure. A few of the numerous approaches for transferring data include
contact and non-contact methods which use wires, radio waves, optical fibers and
even liquid as the transfer media. However, they all suffer inherent drawbacks in
durability, reliability, stability, electromagnetic interference and speed. The system
introduced in this paper alleviates many of these issues by employing a wireless
through the air optical solution.
