Abstract
Terahertz (THz) radiation has the higher penetration to clothing, cardboard boxes, plastic packaging materials and other similar dielectrics. Its lower photon energy compared with X-rays make the detected material and the human being to be not destroyed. THz application in field of security are developed by many countries. In this research, we present a multiband of passive terahertz imaging by the thermal radiation measurement. The Noise Equivalent Temperature Difference(NETD) is obtained. The result shows that NETD of the passive imaging system is 0.8K at 94 GHz, and 1.5K at 250GHz. We found that the main source of noise is the noise from detection circuit. Finally, the improvement methods of detecting sensitivity are analyzed and discussed.
