ABSTRACT:
An angle measuring device for optical angle measurement has a telescope body5which is rotatably mounted around at least one shaft (1, 2; 11), wherein the shaft (1, 2; 11) is rotatably mounted at least two bearing points6, and the bearing points6are at a distance from one another in the direction of the shaft (1, 2; 11). In this case, at least two sensor arrangements for detecting the position of the shaft (1, 2; 11) are respectively arranged at a measurement point along the shaft (1, 2; 11), wherein the measurement points are at a distance from one another in the direction of the shaft (1, 2; 11). At least one of the sensor arrangements has a group of capacitive sensors (7a, 7b, 7c, 7d) which detect a displacement of the shaft (1, 2; 11) in directions perpendicular to the axial direction at the measurement point.
