Energy-resolved neutron imaging (ERNI) techniques offer a unique capability to characterize materials by nondestructively mapping structural and spectral information throughout an entire sample volume. Structural mapping of the external and internal structure provides porosity, defect, and shape information. Spectral data can contain isotopic, temperature, strain, and stress information, as well as crystallographic phase and orientation information depending on the neutron energy region measured. Imaging in the epithermal neutron energy region, for example, provides isotopic composition information. Many nuclides have sharp neutron absorption peaks in the epithermal neutron energy region. This epithermal ERNI technique is often called Neutron Energy Resonance Imaging (NERI).
