  • In order to study the characteristics and the future development direction of terahertz two-dimension imaging methods based on CO2 laser-pumped far-infrared laser source, the basic principle of CO2 laser-pumped far-infrared laser source and two typical lasers,SIFIR-50FPL and FIRL100 made in USA and England respectively, were introduced.Then the domestic and international research results of imaging in recent years and their imaging characteristics were discussed.Finally it was concluded that the long-distance three-dimension image THz radar, the real-time imaging focal plane array (FPA) detection and the real-time image processing and automatic target recognition system were the development trends of the research of CO2 laserpumped terahertz imaging.
