“…Computed laminography (CL) was introduced at synchrotron imaging set-ups [2] to overcome this limitation in specimen geometry. Despite being much less common in the materials science community, the efficiency of synchrotron-radiation CL as a method for non-destructive 3D imaging of flat, laterally extended specimens has already been demonstrated in a variety of scientific areas ranging from microsystem technology [3,4] over cultural heritage investigations [5,6] to paleontology [7]. Recently, a first imple-mentation of CL with neutron radiation was reported [8] providing a sensitivity to chemical elements very different from X-rays.…”

International audienceComputed laminography has been introduced to synchrotron and neutron imaging set-ups to complement computed tomography for three-dimensional imaging of laterally extended (i. e. plate-like) specimens. The wide application field of computed laminography due to different contrast modes (X-ray or neutron absorption and X-ray phase contrast) and spatial resolutions ranging from some 100 down to approximately 0.5 μm is demonstrated. Selected examples from device inspection and from materials science are reported. They outline the interest of the method for nondestructive and in-situ measurements of regions of interest in large planar specimens where engineering-relevant boundary conditions have to be met. With a materials science background, the in-situ investigation of crack propagation in aluminium sheets and carbon-fibre composite panels under mechanical loading is reported

“…Computed tomography (CT) gives additional information on the wooden panels, as it allows for the acquisition of three dimensional data sets reconstructed from a series of X-ray radiographs [73][74][75]. CT data allows to visualize wormholes, cracks and other features of the internal structure of panel paintings.…”

“…For this particular example we see that the holographic approach possibly yields a higher resolution (steeper edges) than the single-distance approach. These phase-contrast possibilities have contributed considerably to provide 3D micro-imaging of flat specimens in a variety of scientific studies, ranging from artwork studies [31] over paleontology [32] to materials science [33].…”

Synchrotron-radiation computed laminography (SRCL) was developed as a nondestructive three-dimensional (3D) imaging technique for flat and laterally extended objects. Complementing the established method of computed tomography, SRCL is based on the inclination of the tomographic axis with respect to the incident x-ray beam by a defined angle. Its ability for 3D imaging of regions of interest in flat specimens was demonstrated in various fields of investigation, e.g. in nondestructive testing, material science and life sciences. We introduce the principles of the method and report on the latest developments of SRCL. The experimental setups at the ESRF beamlines ID19 and ID22NI are dedicated to 3D micro-and nano-scale imaging, respectively, utilising different contrast modes including absorption, phase contrast and fluorescence. Selected examples from materials science outline the potential of the method for an unparalleled nondestructive 3D characterisation of flat specimens.
