Abstract This chapter provides an introduction to neutron tomography. The basic factors influencing instrument design and capability are discussed and the mathematical methods used for image reconstruction are explained. Some of the more promising new techniques, which are likely to have an increasing range of applications, are described in more detail. These include energy (wavelength)-dispersive radiography and tomography, real-time radiography, phase contrast, refraction, and small-angle tomography. In the latter methods, there is an interesting overlap/complementarity between the real-space imaging aspects and the Fourier space imaging aspects, particularly as this gives rise to the possibility of imaging to a resolution of 10 µm or better.
