ABSTRACT:
An electrical parameter imaging apparatus and method includes the acquisition of a charge distribution pattern on an array of electrodes that surround an object being imaged. In addition the exterior boundary, or contours of the object is measured by an array of light beams and associated light sensors. The contour measurement is employed to provide a first estimate of the object geometry needed to compute an electrical parameter image from the acquired charge distribution pattern.
