摘要： 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.

摘要： Method for spectral evaluation of oscillation signals which have been obtained on a rotor blade of a wind power installation with an accelerations sensor. In doing so, instead of the otherwise conventional Fourier transform calculation, the spectral power density is computed. In the evaluation, also signal portions are considered which are not detected in the Fourier transform because they do not go back to oscillations which have been excited in the rotor blade.
