Abstract
Method and apparatus for obtaining a representation of the distribution of electrical impedance within material contained within a containing wall, comprising providing a plurality of mutually spaced electrodes mounted at spaced locations of the wall, electrically insulated from one another and arranged to be in electrical contact with material contained within the wall, applying between an electrical reference ground and each electrode, separately, an input electrical signal which, while applied to any one of the electrodes, causes respective output electrical signals to be generated between the reference ground and each other one of the electrodes, measuring the output electrical signals and processing the resulting measured data to provide a representation of the distribution, within the said material, of its electrical impedance.
