在喷雾系统的研究和开发中，液滴测量是必不可少的。不幸的是，商业化的液滴分级装置通常是昂贵的。廉价的设备将有助于他们的研究处于起步阶段。其中一位作者开发了一个简单的液滴尺寸系统，并已向学术研究人员开放。该系统是基于激光衍射方法，使用图像传感器获得的角度分布的散射光强度从液滴。但该系统有几个缺陷。这主要是由于图像传感器的光强动态范围不足造成的。通过在图像传感器上加一个小的圆形遮阳篷，对系统进行了改进。本文概述了新开发的系统，并给出了试验测量结果。
Drop-sizing is indispensable in research and development of spray systems. Unfortunately, the commercial drop-sizing devices are generally expensive. Cheaper devices would be helpful for the researches on their beginning stage. One of the authors developed the simple system of drop-sizing and has been opened for academic researchers. The system was based on the laser diffraction method using an image sensor for obtaining the angular distribution of scattered lightintensity from droplets. But the system had several imperfections. They were basically owing to the shortage of lightintensity dynamic-range of the image sensor. The system was improved much by putting a small circular awning on the image sensor. The newly developed system is outlined, and the results of trial measurements are presented in this paper.
