Abstract
A capacitive goniometer comprises a plurality of like conductive annular sectors supported in mutually substantially coplanar relationship so as to define an axis which extends through the center of the annulus and is substantially perpendicular to the common plan of the sectors. A conductive member having a generally arc rate outer periphery is supported in spaced confronting relationship with the sectors with the outer periphery of the conductive member not extending substantially farther radially of the axis than the sectors, whereby an electrical signal applied to one of the sectors is capacitivity coupled to the conductive member.
