T1 - Making use of phase-contrast in dimensional muCT-measurements of weakly absorbing objects T2 - Conference on industrial computed tomography (ICT) 2014 (Proceedings) N2 - The effects of refraction (phase-contrast) are normally considered as disturbances in high-resolution μCT-measurements. We show that in the case of small objects with low absorption a single-distance phase-retrieval algorithm not only reduces the edge enhancement, but also raises the signal-to-noise ratio sufficiently to allow dimensional measurements. This is exemplified at an optical element for optical fibre connectors.
