Abstract
Disclosed is a metallic imaging system for detecting and visually displaying the shadow projection of a diamagnetic metallic object immersed in a point source magnetic induction field. In a preferred embodiment of the invention, the object is located intermediate a magnetic induction point source transmitter operating, for example, in the 100kHz range and a magnetic receiver consisting of a scanner adapted for two dimensional movement in a projection plane substantially normal to the axial projection of the magnetic induction field. The output of the scanner comprises magnetic phase and amplitude variation signals which are converted to video signals and thereafter fed to an imaging device for producing a display in the form of a television like visual presentation of the projected magnetic shadow image.
