如何快捷测试大面积烟幕对信息激光的前向透过率和后向散射率是本文的主题。
In thise paper we discuss how to quickly test the laser-transmission coefficient and scattering coefficient of Large area smoke. According to the Tchebycheff best approach principle, we set some sampling positions to measure, then, on the basis of the measurement data, we build transmission function and scattering functions by means of Lagrange polynomials. So we can know the special distribution of transmission coefficient and scattering coefficient by simple test system. At the same time, by the outcome of this testment, we also can compute the formation delayed time and lasting time of this smoke.
