ABSTRACT:
In an angle displacement detector for an optical image stabilization device including a tubular casing which has a chamber containing a sealed-in liquid, a floating body which is disposed within the sealed-in liquid and which is carried in such a way as to be freely rotatable around a given axis of rotation and a detector for detecting a rotation of a floating body around the rotation axis relative to the tubular casing, magnetic elements arranged to have the floating body in a position to permit a measuring action to be adequately carried out at the time of measuring an angle displacement and to adequately keep the floating body in its initial position by a magnetic action when no angle displacement measuring action is required.
