Abstract
An electrical property imaging system includes an array of sensors placed around an object to measure the surface charges thereon as a sinusoidal voltage is applied thereacross. The resulting distribution of charges inside the object are calculated using a stored charge correlation matrix. Electrical property images are produced from the internal charge distribution image.
