Wave-optical description of X-ray phase contrast images of weakly absorbing non-crystalline objects

  • Published:
Il Nuovo Cimento D

Summary

The work deals with the theoretical wave-optical diffraction description of X-ray phase image peculiarities of non-crystalline objects in the Phase Dispersion Imaging technique. The equation for diffracted beam arnplitudeE h (x) coincides with the ones obtained by other authors. The equation for transmitted beam amplitudeE 0(x) contains the additional term with the field derivative∂E 0/∂x. The comparison of computer simulation of the X-ray intensity distribution in the image plane of the test object with the experimental results demonstrates that the theory is satisfactory.
