Abstract-A hybrid continuous-wave terahertz imaging system

A hybrid (active-passive mode) terahertz (THz) imagingsystem and an algorithm for imagingsynthesis are proposed to enhance the THz image quality. The concept of imagecontrast is used to compare active and passive THz imaging. Combining the measurement of the self-emitted radiation of the object with the back-scattered source radiation measurement, it becomes possible to use the THz image to retrieve maximum information about the object. The experimental results confirm the advantages of hybrid THz imagingsystems, which can be generalized for a wide range of applications in the material sciences, chemical physics, bio-systems, etc.
