Beitrag zur kontinuierlichen interferometrischen Untersuchung der Eigenschwingungsformen rotierender Bauteile

The aim of this thesis is to investigate fundamental knowledge for continuous inspection of eigenmodes of rotating objects by means of an electronic speckle interferometer and an optical image derotator. The system suggested consists of a rotor, a derotator and an electronic speckle interferometer. Elimination of the rotation by the derotator enables measuring axial vibration interferometrically. For theoretical investigation of the derotator its function was modelled mathematically. A simulation software was developed and even the real properties of the systems components were implemented. This enabled the analysis of influences of specific quantities separately as well as the study of allowed tolerances. For experimental analysis of the system the electronic speckle interferometer itself was applied for measuring the behaviour of the geometrical relationship of the components. The experimental as well as the theoretical investigation result in complete understanding of the system and an optimised set-up was designed.
