Theory is developed to describe diffraction, in the weak scattering regime, from finite distorted lattices. Correlations between lattice distortions are modeled using an imposed correlation field. The validity of the imposed correlation field is examined. Expressions for the intensity, and the circularly averaged intensity, diffracted from an ensemble of distorted lattices are derived. Calculated diffraction patterns are used to examine the relationship between diffraction and the kind and degree of disorder in a specimen. Implications of this work for inverse problems in x-ray crystallography are discussed.
