  text: "Abstract. The miniaturisation of components leads to new demands on measurement
    systems. One of these is the resolution. As a volumetric analysis method and method
    of non-destructive testing, industrial X-ray computed\r\ntomography (XCT) has
    the ability to measure geometrical features and their corresponding dimensions
    without destroying them and can therefore be used for quality assurance. However,
    the concept of resolution is not trivial for XCT and has not yet been finally
    clarified. In particular, the interface structural resolution, the detectability
    of two surfaces facing each other after surface segmentation, faces a lack of
    a test specimen, a corresponding\r\nmeasurand and a reliable method. Simulation-based
    XCT investigations of a method to determine this type of resolution are presented
    in this article using the geometry of a test specimen that contains several radially\r\narranged
    holes of the same size. The borehole diameters correspond to the distance between
    the holes to investigate the resolvability of surfaces and interfaces. The evaluation
    is based on mean and extreme values of grey value\r\nprofiles between the individual
    boreholes of the reconstructed volume. It is shown that the geometrical detectability
    of the test specimen surface and interface can be extended by a reasonable choice
    of the threshold value for\r\nsurface segmentation within a defined interval.
    With regard to the resolving capability, a distinction is made between assured
    detectability and possible detectability, as well as the threshold value used
    when using the ISO50\r\nthreshold for surface segmentation and measurement chain
    completion. "

  text: <jats:p>&lt;p&gt;&lt;strong&gt;Abstract.&lt;/strong&gt; In this paper, a new
    acoustic sensor principle for coating detection within liquid-filled tubes and
    containers based on mode conversion of leaky Lamb waves is introduced. Leaky Lamb
    waves are excited and detected by single-phase transducers, which are attached
    on the outer side of a tube or container. By transmission time and amplitude measurements,
    coating formation within the liquid-filled tube and container is detected non-invasively.
    This new sensor principle is subdivided into the separate considerations of Lamb
    wave excitation, mode conversion and inverse mode conversion. The Lamb wave excitation
    by a single-phase transducer is visualized by scanning laser Doppler vibrometer
    imaging. The mode conversion process of leaky Lamb waves is measured by membrane
    hydrophone measurements and Schlieren visualization; afterwards, the measured
    emission angles are compared with the theoretical one. The inverse mode conversion
    process of pressure waves back to leaky Lamb waves is visualized by Schlieren
    images. By merging the results of Lamb wave excitation, mode conversion and inverse
    mode conversion, the new sensor concept is explained. Theoretical considerations
    and measurement results of adhesive tape coating inside a liquid-filled plastic
    tube and a liquid-filled stainless steel container verify the new acoustic sensor
    principle. Finally the measuring sensitivity and the technical realization are
    discussed.&lt;/p&gt;</jats:p>
