Nowadays, multiphase flows occur in many different applications in everyday life or industrial context. Consequently, the understanding of transport phenomenolgy between the participating phases is a crucial task of recent and prospective research. When it comes to the optimization of absorption and chemical reaction tasks in process industry, in‐depth knowledge concerning mass transfer is required. The laser‐induced fluorescence (LIF) imaging is therefore a promising optical measurement technique to characterize concentration fields with high spatial and temporal resolution. This review gives an overview of the different fields of research within which LIF measurements are carried out, with focus on gas‐liquid systems. Chances and obstacles of recently publicated results as well as experiences of LIF methods regarding multiphase flows are presented and discussed.
