1. An apparatus, comprising:
a photon emitter configured to emit photons onto a surface of an article; a photon detector array configured to receive photons scattered from magnetic features of the article,
wherein the magnetic features are characterized by transitional magnetic field lines between magnetic domains of the article; and a processing means operably connected to the photon detector array,
wherein the apparatus is operable to detect magnetic anomalies among the magnetic features by a lack of photons scattered from the magnetic anomalies. |
