ABSTRACT
Conventional X-ray microradiography and microtomography are based on X-ray attenuation inside an object. For light objects (in the terms of X-ray absorption) much better way would be to use phase contrast, rather than attenuation contrast. Recently it has been shown that one can obtain phase by using a polychromatic source provided the focal spot size and detector resolution are small enough to maintain sufficient spatial coherence. The technique opens perspectives for high-resolution micro-CT for the objects with low X-ray attenuation, such as diamonds, biomedical objects, etc.
