Abstract

A new nondestructive method for structural imaging is proposed. The method is based on direct measurements of phase and amplitude changes in a 2D x-ray image. A standing wave is formed between two separated crystals allowing high- resolution imaging of the complex refractive index. A comprehensive analysis of the amplitude-phase contrast is possible because of the precisely controlled variation of the phases between the reference and reflected beams from a crystalline mirror.
