| titleOfInvention | System and method for identifying samples having conductive properties |
| abstract | The primary coil (14) of a coil arrangement (14, 16) is fed by a frequency generator (12) having selectable frequencies. The secondary coil (16) is connected to a phase detector (18) which detects phase changes occurring in the signal of the secondary coil (16) when a conductive object (20) is brought into the magnetic field of the primary coil (14). The pure resistance component (R) of the impedance change occurring by bringing the object (20) into the previously calibrated coil arrangement, divided by the frequency (F) supplied changes as a function of frequency and discloses a single peak value at a single characteristic frequency value. These values are compared with characteristic data of known objects, for example stored in a computer. Both values depend on the type and the geometry of the conductive object. For an object made of metal, the characteristic frequency is proportional to the specific resistance of the object divided by its cross-sectional area. Using the device according to the invention, it is possible to obtain accurate information on the type of a conductive object, for example a hidden handgun at the airport. It is also possible to identify various metallic components, if present, in an object. Conductive solutions, animal tissues and others can also be identified. <IMAGE> |
