A simple method for correcting the motion blur effects in molecular tagging velocimetry (MTV) data is developed and evaluated for synthetic MTV data generated from theoretical laminar and turbulent boundary-layer profiles. The analysis shows that the correction method is capable of correcting data in scenarios of fast and slow emission decay. An analytical solution of the model equations shows that the method converges to the gate-centered timing approach in the limit of no emission decay. The effects of motion blurring in two common gating scenarios are also explored, and it is also shown that the analysis is really only needed for the scenario of unequal exposure times. Finally, impacts of motion blurring on the ability to estimate skin friction are discussed, and the new correction procedure outperforms the common method of gate-centered timing.
