Patent ID: 8072228

Claim:
An angle measurement apparatus for optical angle measurement, comprising: a telescope body ( 5 ) which is rotatably mounted about at least one pivot ( 1 , 2 ; 11 ), wherein the pivot ( 1 , 2 ; 11 ) is rotatably mounted at least two bearing locations ( 6 ), and the bearing locations ( 6 ) are distanced to one another in the direction of the pivot ( 1 , 2 ; 11 ), wherein at least two sensor arrangements for detecting the position of the pivot ( 1 , 2 ; 11 ) are arranged in each case at a measurement location along the pivot ( 1 , 2 ; 11 ), wherein the measurement locations are distanced to one another in the direction of the pivot ( 1 , 2 ; 11 ), and wherein at least one of the sensor arrangements comprises a group of capacitive sensors ( 7 a , 7 b , 7 c , 7 d ), which at the measurement location detects a displacement of the pivot ( 1 , 2 ; 11 ) in directions perpendicular to the axial direction.
