IMAGING METHOD AND APPARATUS USING PENETRATING RADIATION TO OBTAIN AN OBJECT PROJECTION

摘要

An imaging system spatially modulates penetrating radiation that passes through an object under investigation. The modulation introduces spatial irregularities which can be deflected while passing through the object under investigation. The deflection of each irregularity can be identified and is converted into contrast of in a projection of the object. One embodiment of the invention includes: a source of penetrating radiation 1, and a modulator 3 for the creation of spatial irregularities; and a detector 5 for measuring transverse translations of spatial irregularities and converting the measured transverse translations into contrast in a projection 8 of object 4.
