Patent ID: 6928886

Claim:
An arrangement ( 10 ) for the detection of relative movements of two objects comprising: four measuring cells ( 20 ) as vertical measuring means for a detection of a relative movement perpendicular to an imaginary plane ( 24 ), with the measuring cells ( 20 ) being arranged in such a manner that their vertical projections onto the plane ( 24 ) are arranged at an identical angular distance from each other about a centre ( 26 ); four measuring cells ( 22 ) as horizontal measuring means for the detection of a relative movement in the imaginary plane ( 24 ), with the measuring cells ( 22 ) being arranged in such a manner that their vertical projections onto the plane ( 24 ) are arranged at an identical angular distance from each other about a centre ( 28 ); wherein at least one privileged direction of the horizontal measuring means includes an angle between 14° and 15° with at least one privileged direction of the vertical measuring means.
