レーザ誘起蛍光法を用いた泥の濃度計測

抄録

The objective of this study is to develop a method to measure the concentration of mud. As the method, the LIF proposed by Kurioka was applied. In this LIF method, Excitation light attenuation isn't predicted by Beer-Lambert's law. In this experiment, the luminosity of the excitation light was obtained by measuring the luminosity of the scattered light by Nylon particles or Kaolinite particles placed in a water tank. It was found that the higher the concentration was between 0[g/l] and 0.3[g/l], the darker the luminosity of the fluorescence was. This relationship was applied in order to measure the concentration. The results showed in which measurement point the concentration was high or low.
