Abstract:The correlativity of extinction coefficients at different wavelengths was get by Mie scattering theory and the laser multipoint fault measuring techniques. The extinction coefficient at the wavelength of 1.06um was measured with the laser remote sensing back scattering hazemeter produced by ourselves. Then the extinction coefficients at the wavelength of 0.532um, 0.86um, 1.57um and 3.47um were inversely calculated real-timely with the correlativity of extinction coefficients at different wavelengths and were compared with the practical extinction coefficient at the wavelength of 0.532um. The results showed that it is feasible to inversely calculate the infrared atmospheric propagation and establish the infrared radiation real-time atmospheric propagation correcting model with the correlativity of extinction coefficients at different wavelengths.
