Abstract:

改变了用中心有孔的环形光电元件接收前向散射光的传统做法,选择采用高灵敏度、低噪声、高分辨率带冷却的CCD采集散射光.采用光导纤维使透射光导出光轴,从CCD采集到的图像得到光强随散射角变化的分布曲线,用米氏散射程序反算出粒径分布;采用CCD为接收设备提高了测量系统的灵敏度和角度分辨率,使测量稀薄液雾或悬浊液的粒径分布成为可能.尽管激光散射粒径测量方法从测量原理上看更加准确,但此测量技术不是利用颗粒的放大成像确定粒径,不直观,通常需要验证激光粒径测量结果的准确性,常采用经其他光学方法测量过的标准粒子验证.提出了一种非光学的准确性验证方法,即利用单分散液滴串发生器产生的大小可控的等直径、等间距液滴串来验证小角弹性光散射粒径测量系统的准确性.
