Patent ID: 8462346

Claim:
A method of obtaining, analyzing and representing data from a specimen comprising: acquiring from the specimen, a signal versus position along a predetermined region of the specimen comprising part or all of a prism; selecting a segment length that is longer than the structural features of the specimen desired to be analyzed and represented and shorter than the predetermined region of the specimen; using the chosen segment length, performing a spatial frequency analysis of the signal over each of adjacent or overlapping segments along the predetermined region of the specimen to obtain values versus spatial frequency over a range of spatial frequencies in each segment; characterizing the spatial frequency analysis of each segment to form a representation of each segment along the region of the specimen; performing the steps above on part or all of multiple prisms to form a two-dimensional representation of the spatial frequencies of the segments; overlaying the two-dimensional representation on another image of the region to illustrate the relationship between the spatial frequencies and the image.
