Abstract
In an exemplary embodiment, in the infrared range, in practicing the method of these teachings, three infrared images of a body having concealed objects are acquired, each image resulting in a response of a detector having a spectral sensitivity in the infrared that is analogous to one of the spectral sensitivities of the color response of the human eye, each image corresponding to a different spectral sensitivity. At least the center of the spectral sensitivity corresponding to the Green response at the human eye is selected to allow increasing the detected radiation difference between the concealed object and the body. The responses of the detector to each of the three images are utilized to provide RGB signals to a display device (a monitor in one instance). The color image displayed in the display device allows identifying the concealed object.
