【摘要】 我们用太赫兹时域光谱技术对不同方法制备的毒品(粉末状和薄片状)进行了检测,分别得到它们在太赫兹波段的吸收谱。通过分析和对比两种不同方法制备的毒品样品的吸收谱,得出样品制备方法对实验结果的影响,进一步保证了样品制备方案的有效性和简单可行性,为实现毒品的探测和无损检测打下基础.更多还原

【Abstract】 Illicit drugs prepared with different method (powder or tablet) were detected using terahertz time-domain spectroscopy technique and spectral absorption in terahertz regain was obtained. Influence on experimental result of different preparation method can be obtained by contrasting and analyzing spectral absorption of illicit drugs to guarantee the feasibility and validity of sample preparation method. The investigation is the first step for detection and non-destructive inspection of illicit drugs.更多还原
