Abstract

High definition impedance imaging (HDII) is applicable, from d.c. upward for electrical, sonic and elasticity signal excitations. At low frequencies, great depth is achievable in contrast to that provided by radar without HDII. The HDII solution process results in a very large and sparse matrix system and associated algorithms provide convergence with few iterations and high image definition. The methodology solves the three-dimensional image solution rather that by solving in slices. HDII image quality results from the number of linearly independent equations resulting from the number of electrodes and linearly independent measurements that are obtained. To construct a standoff (i.e. contactless) system, the three-dimensional vector Helmholtz equation, i.e. the formulation used in antennal analysis, may be employed. To do this, the same basic HDII imaging algorithm, as used for the contact case, is employed for standoff imaging. Over determination can permit significantly refined image quality.
