New trends in neutron imaging

Neutron imaging is a method for non-destructive investigations of objects in science and engineering. Different contrast mechanisms provide information about the interior structure of samples. High-resolution neutron tomography is used for the reconstruction of the three-dimensional matrix of attenuation coefficients in the sample. Energy-selective radiography performed around Bragg-cut-off wavelengths makes structure defects and textures visible. Imaging with polarized neutrons makes it possible to visualize magnetic fields in bulk samples. Examples of different experimental techniques will be presented and discussed.
