摘　　要：Real-time, continuous-wave terahertz （THz） imaging is demonstrated. A 1.89-THz optically-pumped farinfrared laser is used as the illumination source, and a 124 × 124 element room-temperature pyroelectric camera is adopted as the detector. With this setup, THz images through various wrapping materials are shown. The results show that this imaging system has the potential applications in real-time mail and security inspection.Real-time, continuous-wave terahertz （THz） imaging is demonstrated.
