摘要
根据光的后向散射理论,利用光的反射和折射原理,本文提出了一种新的在线测量纸浆浓度的方法———激光光纤测量法。此方法的测量准确度不受流速、温度、压力和纸浆中各种化学离子含量等因素的影响,具有实时性强、测量范围宽、测量准确度高等特点。
This paper gives a new method for measuring the concentration of pulp.The laser and optical fibre measurement is based on the back scattered theory and the principle of reflection and refraction of light. The accuracy of this method has no relation to the flow rate, temperature, pressure and the chemical ions in the pulp and so on. Comparing with other traditional measuring methods, this method is more practical, wider measuring range and higher accuracy.
