摘要
介绍了透射型太赫兹时域光谱系统实验装置和相关参数的提取方法, 分别对绿色和黄色两种烟幕材料在太赫兹波段的光谱特性进行了实验研究, 得到了这两种材料的折射率曲线和屏蔽效能曲线。实验表明, 这两种材料对可见光和红外波段有较好的遮蔽特性, 而对太赫兹辐射的屏蔽效能却较差, 太赫兹侦察探测具有较强的抗干扰能力, 能够弥补传统可见、红外探测系统的不足。
Abstract
A transmission THz time domain spectrum system experimental device and the extraction method of related parameters are introduced. The spectrum characteristics in THz of green and yellow smoke screen materials are researched respectively to obtain the refractive index and shielding effect curves of the two materials. Experimental results show that the two materials have better shielding effect in visible and Infrared band, but has poor shielding effect in THz band. THz wave reconnaissance and detection has strong anti-jamming ability, which can make up the shortcomings of traditional visible and Infrared detection systems.
