【摘要】 泡沫是近年来发现的一种新型宽波段无源光电干扰介质,为评价其红外消光性能,采用 SAT-HY6800型320×240非制冷红外焦平面（UIRFPA）热像仪,给出了利用红外热像图计算红外消光系数的方法。通过对泡沫的红外热像图的分析,计算得到样品的红外消光系数为0.431 m²·g^-1;并采用 OPAG33傅里叶变换红外光谱仪进行了对比,获得了与前者相似的结果。该结果表明,采用 UIRFPA 热像仪用于测定泡沫的红外消光系数是可行的,具有较高的准确度。最后分析了这种测试方法的误差因素,为 UIRFPA 热像仪应用于泡沫红外性能测试提供了指导。更多还原

【Abstract】 Foam is a novel medium of broadband passive photo-electricity countermeasures（PPECM）, a SAT-HY6800 320×240 uncooled infrared focal plane arrays（UIRFPA）thermal imager is applied to evaluate the foams infrared attenuation properties.A method is introduced to get the foams extinction coefficient（EC）by UIRFPA infrared thermographies,so a calculated value of specimens EC is obtained with 0.431 m²·g^-1.And an OPAG33 Fourier transform infrared spectrograph is applied to compare with by a similar result gotten.Those results indicate that UIRFPA thermal imager is viable to test foams EC conveniently with good accuracy.Then the last-mentioned error factors analysis of the method guide the UIRFPA thermal imager application of the foams infrared EC testing.更多还原
