We present what to our knowledge are the first filtered Rayleigh scattering temperature measurements and use them in sooting f lame. This new technique for two-dimensional thermography in gas combustion overcomes some of the major disadvantages of the standard Rayleigh technique. It suppresses scattered background light from walls or windows and permits detection of two-dimensional Rayleigh intensity distributions of the gas phase in the presence of small particles by spectral filtering of the scattered light.
据我们所知，我们首次展示了经过滤波的瑞利散射温度测量结果，并将其应用于有烟灰的火焰中。这种用于气体燃烧二维热成像的新技术克服了标准瑞利技术的一些主要缺点。它抑制了来自墙壁或窗户的散射背景光，并通过对散射光进行光谱滤波，在存在小颗粒的情况下能够检测气相的二维瑞利强度分布。
