Abstract
Se forman imagenes de la superficie de la estructura interna de materiales diamagnetico y paramagneticos al medir, preferentemente con un magnetometro de dispositivo de interferencia de cuantum superconductor (SQUID) (7), las perturbaciones a un campo magnético resultante de las variaciones en la susceptibilidad magnética en un arreglo de lugares en el objeto (3). El arreglo de mediciones de perturbaciones se procesa para generar un mapa de susceptibilidades locales. Para la implementación de tomografía de susceptibilidades se procesan múltiples arreglos de señales de perturbación para una pluralidad de orientaciones relativas entre el objeto, el campo, y los lugares de medición, para generar valores para la susceptibilidad local en lugares seccionados dentro del objeto, tal como a lo largo de un plano seccional seleccionado.
