Introduction
This page covers the current state of knowledge about the through-wall, lens-less imaging technique. This knowledge logically falls into two categories: its capabilities, and the technical details of its implementation. At this point in time, what is known is described in this file, which discusses the known properties of the technique, and currently unresolved issues - which at this point is practically everything. Nonetheless many empirical observations are contained therein that are pretty solid.
As an experimental foray into incorporating videos on this site, here is an example clip of two torsion pendula, one with copper vanes, and the other with non-conductive fiberglass vanes, that are exhibiting the typical kinetic effect induced by the "illumination" energy.
