Development of the neutron phase contrast imaging technique and its application in material science research

dThe neutron interferometry technique provides direct access to phase of the neutron wave. If properly applied, the use of phase information in imaging materials can provide an advantage over normal intensity techniques, which use absorption to provide image contrast. The National Institute of Standards and Technology Neutron Interferometry and Optics Facility has been working on new methods and devices to exploit the neutron phase information to image materials. We will present here the latest results of this effort and an overview of the instruments available at NIST for Neutron Phase Contrast Imaging.
