Real-time continuous-wave terahertz imaging is demonstrated with a 1.63 THz(184.31μm) optically-pumped terahertz laser(OPTL) and a 124×124 element room-temperature pyroelectric camera.Transmission-mode THz imaging is pre-sented for the samples hidden in various wrapping materials.These experimental results reveal the possibility to construct a simple real-time THz imaging system applied to nondestructive inspection.
