ABSTRACT:
An optical device for combining a first light beam and at least one second light beam includes a first beam splitting device, a second beam splitting device and a position detector. The first beam splitting device splits a first reference beam from the first light beam and a second reference beam from the second light beam. The second beam splitting device splits a third reference beam from the first light beam and a fourth reference beam from the second light beam. The position detector detects respective positions of the reference beams so as to enable a respective propagation direction and/or a respective position of the first and/or second light beams to be adjusted as a function of the detected positions of the reference beams.
