Rotary joint system

A rotary joint system comprising:

• a first member rotatable relative to a second member, the first member and the second member coaxially aligned along a central axis and defining a channel therethrough, wherein the channel defines a central channel segment radially extending a defined distance from the central axis and an outer channel segment positioned outwardly of the central channel segment;
• a first communication device positioned proximate to a first end portion of the channel and including a first transceiver and a second transceiver;
• a first reflector fixed with respect to the first member and optically coupled with the first transceiver and the second transceiver;
• a second communication device positioned proximate to a second end portion of the channel and including a third transceiver and a fourth transceiver, wherein the first transceiver and the third transceiver are configured to transmit a first optical signal to one another through the outer channel segment and the second transceiver and the fourth transceiver are configured to transmit a second optical signal to one another through the outer channel segment, the first optical signal offset from the second optical signal relative to the central axis;
• and
• a second reflector fixed with respect to the second member and optically coupled with the third transceiver and the fourth transceiver.

• a first communication device operably coupled with the first member and positioned on a first side portion of the channel, wherein the first communication device defines a first focal axis that is perpendicular to the central axis, wherein the first communication device includes a first transceiver mounted to a first mount and is offset from the first focal axis;
• a first reflector fixed with respect to the first member and configured to reflect an optical signal from the first communication device into the outer channel segment or from the outer channel segment to the first communication device, wherein the first reflector defines a first rim portion, the first rim portion defining a first void at least partially aligned with the central channel segment, and wherein the first member, the first communication device, and the first reflector are configured to rotate a first magnitude of rotation at a first rotational speed from a first position to a second position relative to the central axis;
• a second communication device operably coupled with the second member and positioned on a second side portion of the channel, wherein the second communication device includes a second transceiver mounted to a second mount and is offset from a second focal axis, the second communication device further including an actuator configured to rotate the second mount, wherein the first communication device is configured to transmit the optical signal to the second communication device through the outer channel segment, and wherein the second communication device defines the second focal axis that is perpendicular to the central axis, wherein the second mount is configured to be rotated by the actuator a second magnitude of rotation at a second rotational speed from a first position to a second position relative to the second focal axis, and wherein the first magnitude is equal to the second magnitude and the first rotational speed is equal to the second rotational speed;
• and
• a second reflector fixed with respect to the second member and configured to reflect the optical signal from the second communication device into the outer channel segment or from the outer channel segment to the second communication device, wherein the second reflector defines a second rim portion, the second rim portion defining a second void at least partially aligned with the central channel segment.
