<p>A magnetic detection system (2) to be used by security personnel for the purpose of discovering hidden or otherwise concealed objects being brought into or taken out of a defined or screened area employs magnetic induction sensors (10-19) and, more particularly, a support structure (4) that holds one or more sensors (10-19) in a defined orientation relative to an object to be screened. The system can also include auxiliary components, such as a cancellation unit (200) for nullifying an interfering environmental field, a camera (100) for taking photographs or video of a subject, and presence sensors (105, 106) for use in verifying or signaling the existence of a subject to be screened.</p> |
