It is experimentally established that one can use linear imaging theory with implied kinematical diffraction theory to understand the high resolution image of an amorphous material of thickness 10-20 nm. It is also established that an equivalent thickness of a crystalline material cannot be understood by these models, but instead requires non-linear imaging theory and dynamical diffraction. It is shown here that an amorphous material is a special case where the non-linear and dynamical diffraction solutions reduce to simpler linear and kinematical forms.
