ABSTRACT:
Device for determining the orientation of an axis, mobile about a point, of a solid in rotation about this axis, particularly a gyroscopic spinner, wherein said device comprises a portion of sphere centered on said point of said axis, of which the surface comprises at least two parts which are respectively absorbent and reflecting for a given radiation, and sensor means sensitive to the radiation reflected by the sphere, the reflecting and absorbent parts being shaped so that the sensor means deliver signals characteristic of the orientation of said axis.
