Abstract
We analyse the possibilities of using a new kind of Bragg Fresnel Multilayer Lens that we have designed in order to improve image contrast^[1]. We discuss the aberrations and the dynamical properties of this lens on the base of a recently developed dynamical theory^[2] and of the data from the first imaging tests that we have performed. The principle of the optimal configuration for utilisation of these lenses is given.
