The observation of neutron interference by using a crystal interferometer having a separate analyser opens the way to the construction and operation of interferometers with vast arm separation and length. Setting the design specifications requires a three-dimensional dynamical-theory model of their operation. In this paper, we develop the needed three-dimensional mathematical framework, which also comprises coherent and incoherent illuminations, and apply it to study the visibility of the interference fringes.
