Abstract

In this paper, we propose a new measurement scheme, called phase-stamp imaging 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 light spot 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 apply this scheme to fluid flow measurement. We show some experimental results and confirmed its performance.
