ABSTRACT:
A device determining the orientation of a first solid body with respect to a second or reference solid body. Each body is filled with sets consisting of an optical source and a detector of optical radiation, so as to define at least two straight lines having a direction u and v joining two pairs of sources (S.sub.mi, S.sub.fj), the sources (S.sub.mi) relating to the first solid body and the sources (S.sub.fj) relating to the reference solid body. The device includes means to compute the parameters of orientation of the first solid body with respect to the reference solid body from the coordinates of the vectors u and v. Applications: Determining the orientation of a helmet of the pilot of an aircraft or helicopter with respect to a cockpit.
