Optical communication device for rotary motion assemblies

摘要

An optical communication between a first and second body portion connected by a rotatable member is established. A first optical fiber is attached to the first body portion and a second optical fiber is attached to the second body portion in a manner to allow the first and second optical fibers to be co-aligned with each other and with the rotatable member axis of rotation within the rotatable member. An optical signal emitted from a source on an input circuit board on the first body will transfer through the first optical fiber and be transmitted from the first fiber to the second optical fiber while concentrically aligned within the rotatable member, establishing optical communication between the source on the first body portion and a display device on the second body portion.
