High-resolution time series particle image velocimetry (PIV) has been developed for measurements of turbulent flows. Velocity measurements up to 300Hz with 3969 vectors are successfully conducted in a turbulent mixing layer. New algorithm for the reduction of spurious vectors is also proposed based on the characteristics of the time series PIV. The developed time series PIV measurement is applicable to turbulent flows which show -5/3 law in the inertial subrange.
