碳纳米管对信息激光的消光系数测试研究

消光系数是表示烟幕干扰材料消光性能的重要参数,研究测试了三种不同尺寸的碳纳米管对1.06μm激光的消光系数。利用室内大型烟箱,根据Lambert-Beer定律,通过测量激光透过率和烟幕质量浓度,得到了不同时刻的碳纳米管烟幕对激光的消光系数。结果表明消光系数是一个变量,随碳纳米管材料的时空变化而变化。三种尺寸的碳纳米管对1.06μm激光的平均消光系数分别为1.3568 m2/g、1.3008 m2/g和1.6408m2/g,表明碳纳米管对信息激光具有显著的消光效果。

Study and test on extinction coefficient of carbon nanotubes to information laser

The mass extinction coefficient of smoke interference material is an important physical parameter for extinction performance.The mass extinction coefficients of three kind size carbon nanotubes to 1.06μm laser were tested.According to Lambert-Beer law,by testing laser transmission coefficient and smoke density in a smoke chamber,the mass extinction coefficients of carbon nanotubes to 1.06μm laser were calculated.The results showed the mass extinction coefficient of carbon nanotubes was variable,which changed with the space-time variety of carbon nanotubes materials,average values of it for each kind size carbon nanotubes were 1.3568 m2/g,1.3008 m2/g and 1.6408m2/g respectively.The test results indicated that carbon nanotubes have excellent extinction capability to 1.06μm laser.
