An optical probe capable of measuring local void fraction and interface velocities in water-air or water-steam environments was developed, constructed and calibrated in an air-water loop. The probe was found to be sensitive to both the interface velocities as well as the phase present at the probe tip. A possible explanation for the dependence of the output on the bubble velocity was related to a thin water film left on the probe tip during the passage of the bubble, and whose thickness was increasing with the bubble velocity. In order to study the various probe tip geometry response characteristics, a computer program was developed.
