摘要
利用返波振荡器作为太赫兹波辐射源搭建了双路比较透射式葡萄糖水溶液浓度测量系统。测量了D-葡萄糖、D-(+)-葡萄糖、α-D-葡萄糖3种葡萄糖溶液,实验结果表明该测量系统能够有效地克服太赫兹辐射源功率波动对测量的影响,提高测量精度。该系统结构简单、测量快速、准确,可推广应用于其它溶液或气态、固态物质的测量。
A terahertz two-path transmission system for the concentration measurement of glucose solution is established with backward wave oscillator(BWO) as the terahertz source, and three different glucose solutions such as D- Glucose, D-( +)-glucose, a-D-Glucose are tested as well. The experimental results demonstrated that such kind of measurement system could avoid the influence of the power fluctuation of the THz source, thus improving the measurement accuracy. The measurement system could be used either in solution, or in gas, solid samples.
