<p>An optical rotating joint 2 provides redundancy for camera sensor signals to be passed through an optical rotating joint 2 by passing signals from a plurality of camera sensors 28, 30 via an optical changeover switching arrangement 70 to the optical rotating joint 2; and/or passing signals for a plurality of camera sensors 28, 30 toward the camera sensors 28, 30 from the optical rotating joint 2 via an optical changeover switching arrangement 70. The 10 signals may be sensor control signals or sensor output signals to/from a plurality of sensors 26, 28, 30, for example camera sensors. The apparatus may have one or more wavelength division multiplexer 68 and/or wavelength division demultiplexer 66. The device may convert electrical signals to and from optical signals and may use optical circulator 64.</p> |
