为了获得固体发烟剂烟雾对几种光学波段的衰减数据, 针对发烟剂的特定成分, 采用烟箱法对其产生的烟雾在可见光0.4 μm~1 μm宽波段、1.06 μm激光波段、10.6 μm激光波段和远红外8 μm~14 μm波段进行透过率测试, 获取3种干扰剂烟雾对不同波段的质量消光系数, 得到4种波段在不同浓度不同干扰剂下的3组透过率曲线。测试结果表明: 在4.8 m烟道上、发烟弹烟雾浓度<1.094 7 g/m3的条件下, 10.6 μm激光透过率较1.06 μm激光高出一倍; 红外热像仪的功用远优于硅CCD相机。

In order to obtain attenuation data of several wavebands permeating smog of solid smoke agent, the smog transmittances of 3 smoke agents in 0.4 μm~1 μm visible light waveband, 1.06 μm laser wavelength, 10.6 μm laser wavelength and 8 μm~14 μm far-infrared waveband were tested by the aid of a smoke-box, through which we got the mass extinction coefficients of 3 kinds of interference agent smog in several specified wavebands, and acquired 3 groups of transmittance curves in 4 kinds of wavebands permeating different smog densities with different interference smoke agents. The tested data indicates that the transmittance of 10.6 μm laser is twice as much as that of the 1.06 μm laser in the condition of 4.8 m smog passage and the smog density of smoke agent less than 1.094 7 g/m3 ; And the infrared camera functions are much better than the silicon charge coulped device( CCD) camera.
