摘要：
A method of evaluating a composite structure in which a portion of the structure is imaged and subsequently transformed to provide a 2D output of the angular distribution of features, eg a 2D FFT. A weighting function is applied to the output to compensate for variation in the angular density of pixel population. The weighted output is then used to provide an angular distribution of feature intensity. The structure can be imaged in two or more intersecting planes to allow a 3D determination of feature direction to be obtained.
