摘要

太赫兹宽谱源是指能够产生较宽频谱覆盖范围的太赫兹辐射源,近年来其相关研究受到越来越多的关注。太赫兹宽谱具有能量低,穿透性强和频谱覆盖范围宽等优点,在生物和医学成像、安全检查、化学成分分析等领域具有很大的潜在应用价值,因此研究太赫兹宽谱源对于推动上述领域的进步具有重要的科学意义。本文基于光学辐射源、电子学辐射源、热辐射源这3种太赫兹宽谱源,从产生机理、研究进展以及未来发展趋势对这3种方法进行分析和总结,对比了各自的优、缺点和应用范围。

Abstract

Broadband Terahertz(THz) source can generate a broad THz spectrum, which has been paid more and more attention in recent years. Broadband THz wave has the advantages of low energy, strong penetrability and broadband frequency, which indicates great potential applications in the fields of biological and medical imaging, security check, chemical analysis and so on. In this paper, three broadband THz sources of optical radiation source, electronics radiation source and heat radiation source are analyzed and summarized according to the mechanism of generation, research progress and future development trends. The advantages and application ranges are contrasted as well.
