From: A high visibility Talbot-Lau neutron grating interferometer to investigate stress-induced magnetic degradation in electrical steel

Figure 4

Visibility map of the grating interferometer as determined at a wavelength λ = 4 Å using grating G0 with a duty cycle DC0 = 0.18. The average visibility over 75% of the field of view is V ≃ 0.74. The area is designated by the dashed line. The visibility degrades slightly towards the boundary of the FoV because the beam size has been limited by an aperture to reduce background.
