使用太赫兹光谱的粒子表征
Particle characterization using THz spectroscopy
摘要：
太赫兹消光光谱扩展了紫外-可见和近红外光谱，以表征从细粉末和灰尘到沙子，谷物和颗粒状材料的颗粒。我们提取的干涉结构的第一个峰的光谱位置和尺寸分布的可见性的细波纹结构中测得的消光光谱的颗粒尺寸。因此，我们可以展示一种从单次测量中快速确定这些参数的方法。
英文摘要：
THz extinction spectroscopy extends UV-Vis and NIR-spectroscopy to characterize particles from fine powders and dust to sand, grains and granulated materials. We extract particle sizes from the spectral position of the first peak of the interference structure and size distributions from the visibility of the fine ripple structure in the measured extinction spectra. As such, we can demonstrate a route for a quick determination of these parameters from single measurements.
