An interface for transferring data between a non-rotating body and a rotating body of a sensor assembly using a bidirectional communication link. For instance, the interface may include a first data transmitter coupled to the rotating body and configured to transmit first data signals representing sensor signals generated by the sensor assembly. A first data receiver is coupled to the non-rotating body and configured to receive the first data signals via a first wireless coupling. The interface further includes a second data transmitter coupled to the non-rotating body and configured to transmit second data signals. A second data receiver is coupled to the rotating body and configured to receive the second data signals via a second wireless coupling. In some instances, the first data signals may be transmitted using a first wavelength and the second data signals may be transmitted using a second, different wavelength.
