基于T矩阵法,选取双波长入射光,对火灾烟颗粒与非火灾烟雾颗粒的光散射矩阵进行了详细的数值计算和比较分析.结果表明,入射光波长改变时,烟颗粒光散射矩阵元素的变化明显不同于非火灾烟雾颗粒.选用双波长脉冲激光入射,通过检测合适的光散射矩阵元,结合异或逻辑运算,可区分火灾烟雾颗粒和非火灾烟雾颗粒,降低非火灾烟雾颗粒引起的误报.

Using the T-matrix method, detailed numerical computation and comparative analysis on the distributions of light scattering matrix of fire smoke particles and non-fire smoke particles are carried out. The results show that when the wavelength of incident light changes, the degrees of variation on elements of fire smoke particles are different from those of non-fire smoke particles. By using dual-wavelength pulsed laser as incident ligh, through detecting appropriate element of light scattering matrix and combining XOR logical operation, the fire smoke particles can be distinguished from non-fire smoke particles, thereby reducing the misinformation caused by non-fire smoke particles.
