X-RAY AND NEUTRON DIFFRACTOMETRIC IMAGING OF THE INTERNAL STRUCTURE OF OBJECTS

摘要

A method and device for examining the internal structure of an object uses diffracted x-rays or other penetrating radiation. In one embodiment spatial filters (120, 130) proximate to a source of radiation (110) transmit an array of divergent pixel-beams (133), which irradiate an object (140) being examined. The object absorbs, refracts, diffracts and incoherently scatters radiation from the pixel-beams. Spatial filters (150, 160) proximate to a detector (170) block undeflected and unrefracted radiation which exits the object. The detector separately measures diffracted radiation from each pixel-beam.
