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 infrared laser extinction characteristics of expanded graphite smoke screen, based on the analysis of extinction mechanism of expanded graphite smoke screen, the average smoke density and average laser transmittance at different time intervals were obtained. The mass extinction coefficients of 10.6μm far-infrared laser were 1.1498m 2 / g and 0.8205m 2 / g, respectively. The results show that the expanded graphite smoke curtain has good extinction and interference effects on two wavelengths of infrared laser and has broad application prospects in the field of photoelectrical confrontation.
