Abstract
A new radiography method which utilizes contrast enhancement mechanisms with highly collimated X-ray beams without optics to achieve high imaging resolution and improve the time resolution is disclosed. This invention includes irradiating the object with an unmonochromatized beam, specifically highly collimated synchrotron radiation, and detecting an unmonochromatized beam image after the unmonochromatized beam has passed through the object. With compact design, a system for imaging an object with very high resolution, X-ray radiography with a wide range of X-ray sources, such as synchrotron radiation, without any sophisticated X-ray optics is also disclosed. This invention may achieve real-time images with micrometer resolution.
