We demonstrate the development and application of a low-cost smartphone turbidimeter system to be used on water samples collected from natural resources. The proposed system depends on the spectroscopic measurements of both forward- and side-scattered light. A custom-designed cradle was fabricated using 3D printing, and plastic optical fibers were used to couple light from the smartphone's built-in flash and transmit the collected scattered light to the camera sensor. The performance parameters of the smartphone turbidimeter were investigated and compared to commercial systems, and the lowest limit of detection was found to be 5.58 NTU for forward-scattered detection. The results obtained in the proposed scattered-light-based spectroscopic turbidimeter and the practicality achieved by this extremely low-cost device will have a great impact on water science and technology.
我们展示了一种低成本智能手机浊度计系统的开发与应用，该系统用于对从自然资源采集的水样进行检测。所提出的系统依赖于对前向散射光和侧向散射光的光谱测量。使用3D打印制造了一个定制设计的支架，并使用塑料光纤耦合来自智能手机内置闪光灯的光，并将收集到的散射光传输到相机传感器。对智能手机浊度计的性能参数进行了研究，并与商业系统进行了比较，发现前向散射检测的最低检测限为5.58 NTU。在所提出的基于散射光的光谱浊度计中获得的结果以及这种极低成本设备所实现的实用性，将对水科学与技术产生重大影响。
