Abstract
Data obtained by rotating a set of sensors attached to rotatable parts or the like, in order to perform an alignment of such rotatable parts, is organized in three dimensional vector form (triplets). Two components of such a three dimensional vector will relate to observed apparent geometrical shifts and one component relates to an angle of rotation. In order to arrive at an improved “best fit” when evaluating the data, a three dimensional analysis is performed, based on the concept of an elliptical helix, and using spatial filtering or a neural network. For spatial filtering, three dimensional Fourier transforms are used.
