Abstract
A magnetic detection system 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 and, more particularly, a support structure that holds one or more sensors in a defined orientation relative to an object to be screened. The system can also include auxiliary components, such as a cancellation unit for nullifying an interfering environmental field, a camera for taking photographs or video of a subject, and presence sensors for use in verifying or signaling the existence of a subject to be screened.
