In the present experiment, a handy apparatus is made to observe the transient cavitation bubble motion. The bubble motion is optically observed by a CCD linear image sensor, which is driven by high sampling frequency of 4 MHz. The output data of the CCD sensor are directly sampled by an A/D converter and buffer memory system and transfered to a microcomputer. The sampling speed of the apparatus for one-dimensional data is about 37 microseconds, which corresponds to a high-speed photograph of about 27000 frames/s. The apparatus is applied to observe the motion of a spark-induced cavitation bubble near solid boundary and it is confirmed that the apparatus is very useful to observe the transient cavitation bubble motion. Moreover, some new facts about the transient cavitation bubble motion near solid boundary are confirmed by the present experiment.
