| 中文摘要: |
| 针对固体、液体不同形态易燃易爆危险物品准确识别的要求，设计并搭建了多组件太赫兹时域波谱仪。用该波谱仪检测了两种不同形态的易燃易爆危险品。测试结果表明，该波谱仪在0.1～2 THz频谱范围内检测危险品时都能得到明显的特征吸收峰，因此可以使用该波谱仪识别不同形态的危险品，并为公共安全检查提供一种新的方法。 |
| 英文摘要: |
| A multi-modules all-fiber terahertz spectrum system has been designed and built to meet the requirement of accurate identification for the different forms of flammable and explosive dangerous articles in the anti-terrorism goods detection. After that, two different forms of flammable and explosive dangerous goods have been detected to test the system. The results of the test clearly showed that all of the dangerous goods detected by the terahertz spectrum system have obvious characteristic absorption peaks in the range of 0.1～2 THz. On the basis of the detecting results which have been mentioned above, the flammable and explosive dangerous goods may be identified. What's more, it also offers a possible way for public safety inspection. |
