The potential field sensors (2, 3) may measure the gravity and/or magnetic total field and/or vector and/or tensor data at at 10 least one receiving position with respect to the examined medium. At least one component of the measured potential field in at least one receiver location (potential field data) may be used as at least one artificial source (15) of the potential field data. Artificial sources may produce a back-propagating (migration) field (20). An integrated sensitivity of the potential field data to density and/or magnetization 15 perturbation may be calculated. A spatial weighting of at least one of the backscattering (migration) fields may form a potential field holographic image. At least one desired property of the medium, such as density and/or magnetization, may be derived from this holographic image.
