摘要
文中分析了纳米石墨作为烟幕干扰材料的吸波特性,在喷洒纳米石墨质量不同的情况下,利用烟幕箱测试了1.06μm和10.6μm两种波长激光透过率与时间的关系曲线,用滤膜称重法测量了纳米石墨烟幕在不同时间段的质量浓度,从而测得了纳米石墨对两种红外激光的平均质量消光系数,分别为1.2791m2.g-1和1.0252m2.g-1,表明纳米石墨对红外激光具有显著的干扰效果。
Smoke is a simple and effectual means of laser passive interference. The wave absorption property of nanographite as interference material of smoke screen was analyzed. Under insuffiating different mass of nan-graphite in a smoke chamber, the relation curves between transmission rate of 1.06μ m and 10.6μm laser and time were tested, and with method of weighing dialyser the mass concentration was measured in different moments. So the average mass extinction coefficients of nano-graphite to 1.06μm and 10.6μm laser were calculated,which were 1. 2791m^2 .g^-1 and 1. 0252m^2 .g^-1. The experiment results showed nano-graphite had excellent interference capability to infrared laser.
