title = "Origin of pseudo-variation in high resolution neutron grating interferometry",
abstract = "During neutron grating interferometry measurements with a highly collimated neutron beam a pseudo-variation becomes visible in the acquired data. This pseudo-variation prevents the quantitative analysis of the acquired data, as the measured dark field data depends now on both the ultra-small-angle scattering as well as the properties leading to the pseudo-variation. In the following, the origin of this variation and dependence on the collimation of the neutron beam is explained. It will be shown how by changing the stepped grating in an interferometry scan this variation can be eliminated.",
