Abstract
An angle measuring device for optical angle measurement has a telescope bodywhich is rotatably mounted around at least one shaft (), wherein the shaft () is rotatably mounted at least two bearing points, and the bearing pointsare at a distance from one another in the direction of the shaft (). In this case, at least two sensor arrangements for detecting the position of the shaft () are respectively arranged at a measurement point along the shaft (), wherein the measurement points are at a distance from one another in the direction of the shaft (). At least one of the sensor arrangements has a group of capacitive sensors () which detect a displacement of the shaft () in directions perpendicular to the axial direction at the measurement point.
