ABSTRACT:
Determining a displacement of a substantially rigid item relative to a frame of reference between a first time and a second time is described. At the first time, a first set of pointwise measurements of a physical property of the item taken at a plurality of fixed locations relative to the frame of reference is acquired. At the second time, a second set of pointwise measurements of the physical property taken at the plurality of fixed locations is acquired. A first matrix derived from the first set of pointwise measurements is compared to a second matrix derived from the second set of pointwise measurements to determine the displacement.
