Non-destructive X-Ray testing of complex mechanisms and devices

Abstract

X-ray tomography becomes a wide-spread non-destructive testing method. Flexibility of the reconstruction algorithms makes possible to apply 3D tomographic analysis to complex mechanisms and systems and detect defects of different types. For instance, this opportunity allows to solve geometrical problem, when the size of the investigating sample exceeding dimensions of the setup. This paper proposes to use non-standard geometry of tomographic scanning and backprojection algorithm optimized for this case to solve previously mentioned problem. Producing and assembling of complex space systems and mechanics requires the testing procedure at each step of the technological process: for separate parts of mechanism as well as for assembled system or device. Presented approach prospectively fits for this task.
