Patent ID: 8335409

Claim:
Optical rotary joint comprising at least: a first collimator arrangement for coupling-on a first set of light-waveguides comprising at least one light-waveguide; and a second collimator arrangement for coupling-on a second set of light-waveguides comprising at least one light-waveguide, which second collimator arrangement is supported to be rotatable relative to the first collimator arrangement about a rotation axis; wherein at least one MEMS (Micro Electro-Mechanical System) mirror array is provided between the first set of light-waveguides and the second set of light-waveguides; and at least one control unit is provided for controlling the at least one MEMS mirror array to deflect light from the at least one light-waveguide of one set of light-waveguides into a given light-waveguide of the other set of light-waveguides independently from rotational movement of the second collimator arrangement relative to the first collimator arrangement.
