Abstract
An optical rotary joint includes a first collimator arrangement for coupling on first light-waveguides, and a second collimator arrangement for coupling on second light-waveguides, with the second collimator arrangement being supported to be rotatable relative to the first collimator arrangement about a rotation axis. The collimator arrangements include collimators with an actuator that is adjustable along two axes. A control unit controls the actuators so that mechanical tolerances are compensated, and optical transmission loss between the collimator arrangements is minimal.
