TOMSK, Mar 15 – RIA Tomsk. Scientists of Tomsk state university (TSU)
are working on radiowave system which will allow to receive 3D-radio
images of passengers and to identify, whether they bring prohibited
items – for example, weapon, associate professor of radiophysics
department of Faculty of Radiophysics Sergey Shipilov informed RIA
Tomsk.
Earlier it was reported that TSU Siberian Physicotechnical
Institute created "Radioglaz-Antishahid" – a radar with reflector in
diameter of 160 centimetres which allows through a wall and on distance
more than 10 metres to find out the hidden electronic devices on the
human body.
"The basic principle (for the new device) is based on
the principle of "smart" focusings of the electromagnetic field in a
set point of space through the use of special reflective grating which
can quickly scan the person. On the basis of this algorithm forms
3D-image on which the operator can see hidden on human body objects", –
said Shipilov.

He explained that the device represents a complex
from receiver-transmitter and reflective grating that provides quick
focus and creates a 3D-image of passengers, based on the reflection of
the radio emission from objects. Such a scanner can detect and
accurately indicate the location of dangerous objects, consisting of
various materials, – for example, cold weapon. At the same time
radio-waves do not cause harm to the organism of the checked person.
The
interviewee of agency specified, that both "Radioglaz", and the
developing device is directed to work in places where it is necessary to
detect dangerous object in the inspection of a large number of people –
in airports, shopping malls or stadiums. However they differ on some
"technical parametres".
According to Shipilov, in the world there
is only one analogue of the developing device – the scanner working not
on x-ray, but on radio-waves. However the import device is not applied
anywhere because of its high cost.
