The new Multi-Spectra Tomography (MSP CT) enables high-resolution, low-artifact measurements of difcult-to-penetrate workpieces and assemblies. Previously, measurement accuracy was low, for example, when measuring larger cast aluminum workpieces due to severe artifacts. Measurements with low power and a small focal spot were time-consuming and resulted in high structural resolution but strong artifacts. High power with a correspondingly larger focal spot increased measuring speed but decreased tructural resolution.
With the new MSP CT, a high-resolution measurement with low voltage and a fast measurement with high voltage can now be combined into a high-resolution, lowartifact measurement. For this purpose, the parameters of the X-ray source can be varied, for example for a high-resolution measurement with low power and low voltage and a fast measurement with high power and high voltage. It is also possible to use two diﬀerent X-ray sources, such as a microfocus transmission tube for high resolution and a macrofocus reﬂection tube for fast measurements.
n this way, even small structures on workpieces made of several materials that are difcult to penetrate can be measured, e.g., gap dimensions of the mounting position between the printed circuit board and the corresponding plastic enclosure.
