A method to observe sonoluminescing single-bubble motion has been studied experimentally. The measurement of the bubble size is performed using a light scattering method, but it is rather troublesome to arrange the optical axis precisely. This paper describes a method for the simultaneous observation of bubble shape and measurement of the bubble radius by the light scattering method. This optical system consists of a beam splitter inserted between a lens and the CCD camera, and a photomultiplier tube (PMT) is mounted at the beam splitter. Then, the optical sensing system is positioned easily by monitoring the bubble image. Moreover, when an optical filter is appended, it is possible to capture the bubble image even with the scattered laser light. The bubble radius is measured by light scattering at the interval of the successive flash lights. It is confirmed that this system is useful for the simultaneous observation of the bubble size, shape and its translational motion.
