Metal Trace & X-Ray Detectors

Metal Detectors:
Metal detectors use electromagnetic fields to detect the
presence of metallic objects. They exist in a variety of
walk-through, hand-held, and vehicle-mounted models and
are used to search personnel for hidden metallic objects.
Metal detector uses an oscillator and ‘transmitter’ coil
to generate a high frequency magnetic field within a screened
enclosure; the aperture. Two ‘receiver’ coils receive a signal.
When something magnetic passes through, the magnetic field is
strengthened, causing an output from the receiver circuit.
When something non-magnetic, but conductive, passes through,
the magnetic field is weakened, causing an output from the
receiver circuit.

Explosive and Narcotics Trace Detectors:
Explosive detection and Narcotics trace Detection are a
non-destructive inspection process to determine whether a
container contains explosive material or narcotics. Explosive
detection is commonly used at airports, ports and for border
control etc.
Several types of machines have been developed to
detect trace signatures for various explosive materials. This
equipment uses technology similar to Gas Chromatography, known
as Ion trap / Differential Mobility Spectrometry. Amplifying
Fluorescent Polymers are also being investigated for detecting
explosives.

X-Ray Detectors:
An X-ray machine utilizes electromagnetic radiation to produce
an image of an object, usually with the purpose of visualizing
something located below the object's surface (Explosives,
narcotics or weapons etc).
Specially designed X-ray machines can detect explosives by
looking at the density of the items being examined. They use
Computed axial tomography based systems that are enhanced with
dedicated software, containing an explosives threat library
and false - color coding, to assist operators with their
dedicated threat resolution protocols.
