Abstract
The general field of the invention is that of optical position/orientation devices for a helmet and more particularly those whose helmet comprises neither emitters, nor receivers but solely passive optical components, detection of which is ensured by fixed opto-electronic means outside the helmet. The optical component for the optical device for detecting position/orientation of a helmet according to the invention comprises a particular 'optical cube corner'. It comprises a prism in the form of a trirectangular trihedron, each of the three plane surfaces of the trihedron comprising a blade with plane and mutually parallel faces, the first face being coincident with the plane surface on which it rests, the interface between this first face and said surface comprising a semi-reflecting treatment.
