摘要：
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. (C) 2003 American Institute of Physics.
