摘　　要：太赫兹波(terahertz waves)位于红外波段与微波波段之间,相比其他波段具有高透射性、低能量性、相干性、指纹光谱以及瞬态性等特点。随着太赫兹成像技术在空间通信、雷达探测、航天航空以及生物医疗等领域的广泛应用,已经表现出传统成像技术(如可见光、超声波和X射线成像)无法比拟的优势。本文首先对太赫兹时域光谱(THz-TDS)成像技术以及室温(非制冷)微测辐射热计太赫兹成像技术的发展现状进行介绍,再介绍太赫兹成像技术的典型应用,最后指出太赫兹成像技术在发展中存在的限制因素并给出合理的建议。Terahertz(THz)waves are located between the infrared and microwave bands.Compared with other bands,they have the characteristics of high transmission,low energy,coherence and transient nature.With the widespread application of terahertz imaging technology in the fields of space communication,radar detection,aerospace and biomedicine,it has been shown that THz imaging offers advantages over traditional imaging technologies(such as ultrasonic imaging and X-ray imaging).This paper first introduces the development status of THz time-domain spectroscopy(THz-TDS)imaging technology and room temperature(uncooled)microbolometer THz imaging technology.Subsequently,typical applications of THz imaging technology are presented.Finally,the limiting factors of THz imaging technology are discussed.
