Security body scanner employing radiant energy and associated detecting method

A detector comprising:

• two opposite side panels fixed relative to each other and together delimiting a passage;
• radiant energy transducers housed in at least one of the side panels;
• and
• a central processing unit configured to send instructions to an individual to be inspected placed in the passage so as to:
• place the individual to be inspected in a first position within the passage between the two side panels of the detector;
• acquire first signals representative of a radiant energy when the individual to be inspected is in the first position;
• place the individual to be inspected in a second position within the passage between the two side panels of the detector, wherein in one of the first and second positions, the individual to be inspected is placed facing one of the side panels and leaves his arms along his body or spreads his arms in the central plane, and in another of the first and second positions, the individual to be inspected is placed perpendicular to the two side panels and moves his arms at a distance from his body so as to place them in front of him or on the sides, at shoulder height;
• acquire second signals representative of a radiant energy when the individual to be inspected is in the second position;
• and
• on the basis of the first signals and the second signals, produce an electronic image so as to investigate whether the individual to be inspected is carrying a target object.
