【摘要】：为了提高颗粒检测实验的抗噪性能,改进Chahine算法引入一维平滑函数。着重分析Mie散射的原理,计算消光系数矩阵。建立颗粒粒径分布软测量模型,测量多个波长下的消光值来获得待测颗粒系的粒径分布曲线;加入不同程度的噪声进行比较,验证Chahine算法的抗噪能力较强,实验结果准确性较高。
[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.
