Wind turbines' rotor blades still are manufactured in quite simple production processes. This leads to a high rate of defectively produced parts. Also, reliable, objective and powerful methods for testing and quality assurance of rotor blades are not yet available. We research solutions to provide three-dimensional X-ray images for those rotor blades by utilizing methods for laminographic imaging which can be applied to such large objects with semi-planar regions of interest. We present our latest research on evaluation of these trajectories concerning the requirements for manipulation systems. Our objective is to identify the necessary setup that will allow us to acquire the three-dimensional images that are needed to automatically analyze rotor blades for different types of defects and especially ondulations in the fiber material by means of X-ray image processing.
