Abstract
A device for determining the position of a first mechanical element relative to a second mechanical element, having a first measurement unit for attachment to the first mechanical element, a second measurement unit for attachment to the second mechanical element, and an evaluation unit. The first measurement unit emits spectrally differing first and second light beams in essentially the same direction and a position-sensitive optical detector. The second measurement unit has a reflector arrangement facing the first measurement unit, in order to reflect the first and second light beams onto the detector. Surfaces facing the first measurement unit being color splitters having different reflectivity/transmissibility for the first light beam and the second light beam. The evaluation unit determines the location of the first and second mechanical elements relative to one another from the incidence positions of the reflected first and second light beams on the detector.
