摘　　要：分析了烟幕激光透过率与红外透过率的对应关系,提出了利用相邻波段红外透过率推算同样光学路径激光透过率的多项式拟合方法,开展了实验研究.结果表明:特定波长的激光透过率与相应红外波段透过率利用二项式拟合,其透过率计算误差在3%以内.The corresponding relation of laser transmittivity and infrared transmittivity was analyzed. A polynomial fit algorithm was introduced for reckoning laser transmittivity by infrared waveband transmittivity in the same optical paths. The tested results show that the fit error is less than 3% ,as the laser wavelength is in or near infrared waveband.
