In this paper, a research of PMMA optical fiber reflectivity changing along with the angle of tips has been studied. A typeof integrated conical fiber probe is designed. Nine angles of cone fiber tips were fabricated and tested in 0.4 L /mincontinuous uniform bubble flow (air) in this study to validate the performance of each cone angle. A simulation model ofPMMA optical fiber tip was established based on physical properties of fiber to simulate the reflectivity of different angletips set into gas/liquid environment. The first and second high peaks of experimental data agree well with the positions ofthose calculated using the simulation.
