Terahertz imaging makes it possible to acquire images of objects concealed underneath clothing by measuring the radiometric temperatures of different objects on a human subject. Finding objects hidden under clothes is one of key issues of public places security. A possible solution of this problem is a multispectral, terahertz-based screening system with implemented image fusion algorithm. The result of the fusion is a new image which gives more information and is more suitable for human perception. An imaging system is usually composed of various subsystems. Many of the imaging systems use imaging devices working in various spectral ranges. The aim of our studies is to detect and visualize objects hidden under clothing. Detection of potentially dangerous objects is important, but without proper visualization, can be difficult to utilize. Our goal is to build a system harmless to humans for screening and detection of hidden objects using a THz and VIS cameras. The presented system draws attention not only on the properties offered by a single camera but also on the potential of synergetic effects of the system by using the fusion of data registered by different sensor units. In this paper we present the multispectral passive imaging system for hidden threats visualization based on THz and VIS cameras.
