<p>An orientation detector arrangement is provided, which is adapted to detect the orientation of a first component relative to a second component. A preferred embodiment of the arrangement is particularly suited for use during endoscopic surgery. The first component takes the form of a transmitter which may be worn on a surgeon's head, the transmitter being adapted to transmit a plurality of uniquely identifiable signals along mutually diverging beams. Such signals may take the form of visible light of different colours or wavelengths. The second component takes the form of a detector which, in the case that the transmitter transmits signals of visible light, may take the form of a photosensor, which is connected to means adapted to distinguish between the individual signals transmitted by the transmitter. The detector may be connected via a control circuit to an endoscopic camera which is in turn connected to provide an image on a display screen. The detector and the associated control circuit are able to control movement of the endoscopic camera in response to movements of the surgeon's head.</p> |
