Method and apparatus for the promotion of selected harmonic response signals in an article detection system |
摘要 |
An electromagnetic article detection system of the type wherein a saturable magnetic target generates harmonics of an alternating magnetic interrogation field. A magnetic bias means is provided along with the magnetic interrogation field to promote the production of target response particularly at even harmonics, throughout the interrogation region.
