论文摘要
我们证明了THZ成像对冬季小麦叶子的破坏性和非破坏性水状态监测的可靠性和适用性。基于测得的THZ传输幅度,我们发现在自然脱水过程中,远端区域的水分流失小于基底区域的水损失。在脱水和再水后,通过重量计量方法测量的传输THZ信号和水含量水平之间显示了高相关性。获得的结果表明,冬季小麦叶片中的水含量可以使用透射几何形状中的terahertz波,以高精度的精度进行破坏性和无损的测量。
We demonstrate the reliability and applicability of THz imaging for destructive and non-destructive water status monitoring of winter wheat leaves. Based on the measured THz transmission amplitude, we find that the water loss in the distal region is less than that in the basal region during the nature dehydration process. A high correlation is shown between the transmitted THz signal and water content level measured by gravimetric weighing method during dehydration and after rehydration. The obtained results show that the water content in winter wheat leaves can be measured destructively and non-destructively with a high accuracy, using terahertz waves in a transmission geometry.
