Method and device for producing and using localized periodic intensity-modulated patterns with x-radiation and other wavelengths

摘要

A method and device is disclosed for the generation of high-contrast, localized sinusoidal patterns or stepped-intensity modulated patterns from spatially non-coherent or coherent illumination, and using such patterns for imaging the internal features of objects.

1. A system for forming an image of an object, said image including internal features of said object, said system comprising: means for generating penetrating radiation beams; said means for generating having multiple point origins of said beams providing that said beam origins have linear alignment; one or more compound refractive radiation lenses placed between said beam origins and said object; means for supporting said object to provide that said beams are directed through said object and through said one or more compound refractive radiation lenses; said radiation imaging optic arranged to form at least a partial image of said beams origins presented on a detector screen; said partial image including at least one of phase and scattering content of said object's internal features in a direction along the linear alignment axis of said beam origins.
