Here the authors introduce a Fourier based method for phase contrast neutron imaging, report its experimental implementation, and show results for a one-dimensional test phantom. This approach makes use of neutron interferometry to achieve both phase contrast and to spatially code the phase of the neutron with a linear phase grating. The spatial information is recovered from the coherent interference of this phase grating and a spatial phase distribution due to the sample. By moving neutron imaging from real to reciprocal space they avoid the need for position sensitive detectors and improve the potential image resolution.
