Step Through, Please: Metal Detector How Airport

AccessMechanismExampleOperationDesignAlmost all airport metal detectors are based on pulse induction PI . Typical PI systems use a coil of wire on one side of the arch as the transmitter and receiver. This technology sends powerful, short bursts pulses of current through the coil of wire. Each pulse generates a brief magnetic field. When the pulse ends, the magnetic field reverses polarity and collapses very suddenly, resulting in a sharp electrical spike. This spike lasts a few microseconds millionths of a second and causes another current to run th
