Abstrakt

We discuss the applicability of holographically recorded gratings in photopolymers and

holographic polymer-dispersed liquid crystals as neutron optical elements. An experimental

investigation of their properties for light and neutrons with different grating spacings and

grating thicknesses is performed. The angular dependences of the diffraction efficiencies for

those gratings are interpreted in terms of a rigorous coupled wave analysis. Starting from the

obtained results we work out the lines for the production of an optimized neutron optical

diffraction grating, i.e. high diffraction efficiency in the Bragg diffraction regime with moderate

angular selectivity.
