Optical position-measuring device
An optical position-measuring device includes a light source, a measuring reflector movable in space, a detection unit and a light-beam deflection unit that can align at least one beam of rays, emitted by the light source, in the direction of the measuring reflector. The light-beam deflection unit includes a cardan system having two cardan frames. A first cardan frame is adjustable by motor about a first axis of rotation, and a second cardan frame within the first cardan frame is adjustable by motor about a second axis of rotation oriented in a direction perpendicular to the first axis of rotation. The two axes of rotation intersect in a fixed reference point, at which a reference reflector is disposed. A plurality of mirrors are disposed rigidly on the cardan frames, so that the beam of rays can be pivoted about the fixed reference point via the mirrors during alignment.
