【摘要】：為了提高顆粒檢測實驗的抗噪性能,改進Chahine算法引入一維平滑函數(shù)。著重分析Mie散射的原理,計算消光系數(shù)矩陣。建立顆粒粒徑分布軟測量模型,測量多個波長下的消光值來獲得待測顆粒系的粒徑分布曲線;加入不同程度的噪聲進行比較,驗證Chahine算法的抗噪能力較強,實驗結(jié)果準確性較高。
[Abstract]:In order to improve the anti-noise performance of particle detection experiment, the one-dimensional smoothing function is introduced into the improved Chahine algorithm. The principle of Mie scattering is analyzed and the extinction coefficient matrix is calculated. A soft sensor model of particle size distribution was established to obtain the particle size distribution curve of the particle system under multiple wavelengths by measuring the extinction value, and the noise of different degrees was added to verify that the Chahine algorithm had strong anti-noise ability. The experimental results are accurate.
