Refraction of thermal neutrons was used as imaging signal for computerized neutron tomography. Using a special instrument, attenuation and refraction could be observed simultaneously, extracted and separated from each other, and two-dimensional (2D) images reconstructed from pure refraction data. Even in the case of no attenuation contrast, perfect 2D images of objects could be reconstructed using the refraction data only.

    Tomosynthesis is a well known technique for imaging a plane in a target by blurring other planes in the target. Commonly, the tomosynthesis is based on the x-ray absorption contrast. Recently, methods for generating other x-ray contrasts were developed. One of them, the so-called refraction...

    Computed tomography has become a routine method for probing processes in porous media, and the use of neutron imaging is especially suited to the study of the dynamics of hydrogenous fluids, and of fluids in a highdensity matrix. In this paper we give an overview of recent developments in both...
