1. A portable system for detecting a presence of concealed objects, the system comprising:
- a first frame;
a temperature modifying component for modifying a temperature distribution of an emitting body;
said temperature modifying component altering a thermal balance for said emitting body;
said temperature modifying component being operatively connected to said first frame;
said temperature modifying component comprising;
a device capable of directing a stream of gas, heated to substantially a predetermined temperature, at the emitting body;
an image acquisition device receiving electromagnetic radiation from the emitting body and acquiring an image of the emitting body from the received electromagnetic radiation;
said image acquisition device being also operatively connected to said first frame; and
at least one handle attached to said first frame;
a weight and dimensions of said first frame, said temperature modifying component and said image acquisition device being selected to enable portability;
the received electromagnetic radiation from the emitting body, the emitting body having a modified temperature distribution, enabling detection of the presence of concealed objects.

27. A method for detecting a presence of concealed objects, the objects being concealed at locations not accessible for detection by conventional methods, the method comprising the steps of:
-
modifying, utilizing a handheld system, a temperature distribution of an emitting body by directing at least one stream of heated gas at the emitting body;
the modifying comprising altering a thermal balance for the emitting body;acquiring, utilizing the handheld system, at least one image from electromagnetic radiation emanating from the emitting body after the temperature distribution has been modified; and providing, to a component of the handheld system, the at least one image for detection of the presence of concealed objects. - View Dependent Claims (28, 29, 30, 31, 32, 33, 34)
