光纤探测法是测量气液两相流中气泡/液滴(直径、速度和数密度)的一种非常有用的技术，并有望在其他研究领域得到应用。它的基本测量原理非常简单：检测折射率的变化。很难获得关于探头穿透气泡/液滴的准确信息。由于探测信号涉及各种光学信息，还没有研究者能够成功地提取出OFP信号的物理意义。为了提高OFP的测量精度，需要深入了解探测信号与探针-气泡/液滴接触过程之间的关系。通过一种新研制的地层追踪模拟器，对光学信号进行了分析，揭示了两者之间的关系。本研究的目的是在实验结果和数值结果的基础上提高OFP的精度。此外，还将提出OFP在生物技术中的应用。
Optical Fibre Probing (OFP) is a very useful technique to measure bubble/droplet (diameter, velocity and number density) in gas-liquid two-phase flows; furthermore the OFP is hopeful in other research fields. Its basic measurement principle is very simple: detection of change in the refraction indices. Accurate information about the penetration of a bubble/droplet by the probe is very difficult to obtain. Since the probing signals involve various kinds of optical information, no researcher succeeded in extracting physical meanings of the OFP signals. To improve the OFP measurement accuracy, deep understanding of the relationship between the probing signals and probe-bubble/droplet contacting process is needed. Through a newly developed lay-tracing simulator, the author analysed the optical signals and revealed the relationship. The objective of the present study is to improve the accuracy of the OFP, based on experimental results and the numerical results. Furthermore, the application of OFP to biotechnology will be proposed.
