Abstract:
1. A dual optical path rotary joint, comprising: a stationary component having a first optical port and a second optical port; a first rotating component rotatably coupled to the stationary component, such that the first rotating component is rotatable with respect to the stationary component about a rotational axis; and a second rotating component having a third optical port and a fourth optical port and rotatably coupled to the stationary component, such that the second rotating component is rotatable with respect to the stationary component about the rotational axis, wherein the first rotating component and the second rotating component are magnetically linked to synchronize a common angle of rotation of the first rotating component and the second rotating component, but are not otherwise mechanically coupled in rotation, and wherein the first optical port is coupled to the third optical port by a first optical path extending between the stationary component and the second rotating component, and wherein the second optical port is coupled to the fourth optical port by a second optical path extending between the stationary component and the second rotating component.
