Abstract
An optical system, for the remote determination of the position and orientation of a body in a frame of reference, e.g. a helmet within a cockpit of an aircraft, comprises co-operating light emitting means and light sensing means. At least three of one type of said co-operating means are located on the body and scanning optic means are arranged to scan the frame of reference with a pair of planar beams. The planes of the beams are inclined to each other and are arranged to provide a light path between the co-operating means. A signal processing means is operative to provide a signal indicative of the position and orientation of a body and a time during the scan of each respective beam in which the beam is coincident with each of the said means mounted on the body. In one embodiment three light sensing means are located on the body and the planar beams are beams of light from a light emitting means. In another embodiment three light emitting means are mounted on the body and these are scanned by planar acceptance beams on to at least one light sensing means.
