Abstract:
An apparatus for information extraction from electromagnetic energy via multi-characteristic spatial geometry processing to determine three-dimensional aspects of an object from which the electromagnetic energy is proceeding. The apparatus receives the electromagnetic energy. The received electromagnetic energy has a plurality of spatial phase characteristics. The apparatus separates the plurality of spatial phase characteristics of the received electromagnetic energy. The apparatus r identifies spatially segregated portions of each spatial phase characteristic, with each spatially segregated portion of each spatial phase characteristic corresponding to a spatially segregated portion of each of the other spatial phase characteristics in a group. The apparatus quantifies each segregated portion to provide a spatial phase metric of each segregated portion for providing a data map of the spatial phase metric of each separated spatial phase characteristic. The apparatus processes the spatial phase metrics to determine surface contour information for each segregated portion of the data map.
