摘要
为测试膨胀石墨烟幕红外激光消光特性,在分析膨胀石墨烟幕消光机理的基础上,通过测量其在不同时段的烟幕平均质量浓度和平均激光透过率,得到了膨胀石墨烟幕对1.06μm近红外和10.6μm远红外激光的质量消光系数分别为1.1498m^2/g和0.8205m^2/g。结果表明,膨胀石墨烟幕对两个波长的红外激光具有良好的消光和干扰效果,在光电对抗领域具有广阔的应用前景。
In order to test the laser extinction properties of expanded graphite, based on the analysis of smoke extinction mechanism, the laser transmittance curves of expanded graphite smoke versus time on the 1.06μm and 10.6μm laser are tested in the smoke box. The concentrations of expanded graphite smoke at different moments are measured with membrane weighing method. The average mass extinction coefficients of expanded graphite smoke on IR laser are calculated, which are 1. 149 8m2/g, 0.820 5m2/g respectively. The results show that expanded graphite has good smoke interference effect and extinction effect. It has broad application prospects in the field of optoelectronic against.
