Molecular tagging measurement technique is an advanced non-intrusive visualization approach which uses the molecules as the tagging and tracking materials. This technique has advantages in the measurement of complex flow fields such as the boundary layer flow, supersonic turbulence, micro-scale flow and combustion flow, and it owns superiorities in the simultaneous measurement of multi-parameters in the flow field such as velocity field, temperature field and pressure field. In this paper, a comprehensive review on recent advances of molecular tagging measurement is presented, with an emphasis on its measurement fundamentals and approaches. In addition, the factors influencing the resolution and uncertainty of this technique are also discussed. Finally, the applications highlighting the advantages of this technique are shown. This review provides the current situation as well as challenges of this measurement technique, and is expected to promote the extensive applications of molecular tagging measurement technique in both scientific research and industry.
