Claim 0:
1. An optical rotary joint comprising:
a first annular portion having a receiver face substantially orthogonal to a rotational axis of the rotary joint;
a second annular portion configured to rotate with respect to the first annular portion about the rotational axis, the second annular portion having an emitter face substantially orthogonal to the rotational axis and facing the receiver face;
a plurality of optical receivers on the receiver face facing the emitter face; and
a plurality of optical transmit beam launchers on the emitter face configured to transmit optical signals to the optical receivers as the second annular portion rotates with respect to the first annular portion;
wherein the plurality of optical transmit beam launchers are configured to transmit optical signals at two different wavelengths; and
wherein the plurality of optical receivers further comprise one of two different optical bandpass filters to pass a respective one of the two different wavelengths.
