摘　　要：为了实现水体色度的实时在线测量,设计透射式光纤传感器,搭建光纤传感器系统,利用该系统采集色度标准溶液的光谱数据,采用色度学计算方法建立色差与吸光度的相关性关系,并进行多个水样测试验证。试验结果表明色差与色度具有良好的相关性,采用所设计的光纤传感器系统和色差计算方法测量水体色度,速度快、精度高,无二次污染,能较好地应用于水体色度实时监测。In order to implement real-time online measurement of water color, a transmission fiber optical sensor was designed, and a fiber optical sensor system was established. The spectral absorption data of standard color solutions were obtained using this experimental system, and the correlation relationship between color difference and absorbance was established using colorimetric calculation method. The measurement results of water samples showed that the correlation between the color difference and the color was good. Using the optical fiber sensor system and the calculation method of the color difference to measure water color has advantages of fast response, high accuracy and no secondary pollution, they can be well used for real-time measurement of water color.
