Measurements of cavitation bubble dynamics based on a beam-deflection probe

Abstract We present an optodynamic measurement of a laser-induced cavitation bubble and its oscillations based on a scanning technique using a laser beam-deflection probe. The deflection of the beam was detected with a fast quad-rant photodiode which was built into the optical probe. The applied experimental setup enabled us to carry out one- or two-dimensional scanning of the cavitation bubble, auto-matic control of the experiment, data acquisition and data processing. Shadow photography was used as a comparative method during the experiments. PACS 42.62.-b · 47.40.-x · 47.55.dd
