Given a measured diffraction pattern, can one determine the geometry of the diffraction
structure?

Method of Solution:

First one must generate a computer model for diffraction structures and generate data
sets for diffraction structures with different geometric properties.

From the data sets one tries to determine the relationship between the diffraction
pattern and the geometry of the diffraction structure.

If no clear pattern exists, one may have to construct a database of data for the
various geometrical configurations of interest. Comparison of future measurements to the
database determines the geometry of the diffraction structure.
