Optical fiber probing is one of the efficient and reliable measurement methods for gas-liquid two-phase flows. We demonstrate the simultaneous measurement of velocities and diameters of bubbles and droplets using S-TOP and report its excellent performance. In order to realize more high-accuracy measurement, we need to consider a contact position of S-TOP at a bubble surface. In this research, we focus pre-signal which appears when S-TOP contacts with the center region of a bubble, and discuss the relationship between the output voltage of pre-signal and the contact position of S-TOP at a bubble surface. Appling this property cleverly, one can discriminate a contact position.
