In this paper, we propose a new measurement scheme, called phase-stamp particle trajectory velocimetry (PSPTV) using correlation image sensor (CIS). The correlation image sensor, developed by us, is the device which outputs the temporal correlation between incident light intensity and three reference signals which is common among whole pixel. By using the correlation image sensor with the single frequency reference signals, the time at which tracer particle is getting through is embedded in the form of the phase of the reference signals in each pixel. It provides single frame high resolution measurement of the 2D velocity field, and also good time resolution for transient phenomenon. We show some experimental results and confirmed its performance.
