Abstract

Here we introduce a Fourier based method for phase contrast neutron imag-ing, report its experimental implementation, show results for a 1-D test phan-tom, and outline the reconstruction methodology. This new approach makes useof neutron interferometry to achieve both phase contrast and to spatially codethe phase of the neutron with a linear phase grating. The spatial informationis recovered from the coherent interference of this phase grating and a spatialphase distribution due to the sample. By moving neutron imaging from real toreciprocal space (in analogy to Fourier magnetic resonance imaging [1]) we avoidthe need for position sensitive detectors and improve the potential image reso-lution. The ultimate resolution will depend solely on the beam characteristics:intensity, momentum spread, and divergence.
