Abstrakt: The irradiation of an inhomogeneous liquid sample with a long train of short laser pulses and subsequent recording of a histogram of the magnitudes of the acoustic responses can serve as a diagnostic tool for various applications. The absorption of an incident light by a suspended particle may cause a cavitation event. Exploitation of the random cavitation events which, in turn act as effective acoustic radiators, may provide a useful measurement tool rather than an inconvenience. [ABSTRACT FROM AUTHOR]
