摘要
红外消光系数是衡量烟幕对红外遮蔽能力的关键参数,文中提出利用热像仪测得的温度数据,通过计算得到红外辐射能量变化及消光系数的方法,介绍应用情况及测试中应注意的问题。
Anti-infrared extinction coefficient is a key parameter to assess the obscuring performance of smoke-screen, a method to calculate the viriation of radiant energy and obtain the extinction coefficient based on the temperature tested by a thermal imager has been proved, the practical situation and notice in test also has been illustrated.
