An in-line and real time chromatic sensor for liquids based on plastic optical fiber was developed. It uses an air gap, fiber to fiber, transmission principle. Its dependency to turbidity and refractive index is studied and characterized. This information will provide the necessary knowledge for future implementation of more complex auto-compensations routines. Due to the predictable behavior of the sensor to variations of turbidity and refractive index, it is shown that a posterior compensation could be applied for the discrimination of color. The real-time color sensor can be used in different turbid liquids and contain different refractive indices.
开发了一种基于塑料光纤的在线实时液体色度传感器。它采用光纤对光纤的气隙传输原理。研究并表征了其对浊度和折射率的依赖性。这些信息将为未来更复杂的自动补偿程序的实施提供必要的知识。由于传感器对浊度和折射率变化的可预测行为，表明可以在后补偿中应用颜色识别。实时彩色传感器可用于不同浊度的液体，并包含不同的折射率。
