This contribution deals with the dynamics of the penetration of the fine thin sharp tip of a optical fiber probe with the gas-liquid interface at a surface of a gas bubble freely moving in a liquid. Simple experiments were performed where the process under study was monitored with help of two independent sources of information, employed simultaneously. First, the output probe signal (voltage), which reflects the individual steps of the probe passage through the interface. Second, the high-speed video imaging, which gives the detailed optical information the bubble surface puncturing.

Tato práce je zaměřena na dynamiku napichování bublin na aktivní hrot optické sondy. Byl proveden jednoduchý experiment, kdy se sledovaný jev zaznamenával současně rychloběžnou kamerou a optickou sondou. Bylo provedeno vyhodnocení experimentálních dat a srovnání výsledků získaných z nezávislých měření.
