Abstract

The injection-seeded terahertz parametric generator (is-TPG) is suitable for the non-destructive inspection of illicit drugs and explosives concealed in mail because of its high power generation and sensitive detectors. This study examined a terahertz (THz) spectrometry method suitable for the non-destructive detection of chemicals concealed in mail envelopes. We compared the transmission spectra of three saccharides in different covering materials using is-TPG and terahertz time-domain spectroscopy (THz-TDS).

使用注射种子太赫兹波参数发生器无损检测邮件信封中的化学物质
注射种子太赫兹参数发生器(is- tpg)由于其高功率和灵敏的探测器，适用于对匿藏在邮件中的毒品和爆炸物进行无损检测。本研究研究了一种适合于无损检测隐藏在邮件信封中的化学物质的太赫兹(THz)光谱法。我们使用is-TPG和太赫兹时域光谱(THz-TDS)比较了三种糖类在不同覆盖材料中的透射光谱。
