摘要: Conventional radiography seeks to produce, at each location in the image plane, a measure of X-ray absorption object. In this paper, we present method determining much more complete object description point, namely intensity distribution (as function angle) emerging beam. From one can compute many different images, depicting refraction, absorption, and scattering characteristics The is based on acquisition multiple images using monochromator analyzer crystals, followed by deconvolution operation (over pixel. Parameters deconvolved angular are measured obtain various interest. We experimental results obtained X-rays produced synchrotron, along with simulated showing effect noise hypothetical photon-limited imaging situation.
