Abstract
We demonstrate a simple single grating beam modulation technique, which enables the use of a highly intense neutron beam for phase imaging and thus spatially resolved structural correlation measurements in full analogy to quantum interference based methods. In contrast to interferometric approaches our method is intrinsically achromatic and provides unprecedented flexibility in the choice of experimental parameters. Utilizing merely a macroscopic absorption mask unparalleled length scales become accessible. The results presented, including application to a variety of materials, establish a paradigm shift in phase imaging.
