The acquisition of two images back-to-back with as short of a gap in time as possible between the two images is useful for tracking the quickest time-dependent phenomena (e.g. PIV or MTV to measure velocity of flows). It also freezes out not quite as fast time-dependent phenomena (e.g. taking a background (first) image and a “laser on” (second) image for removal of turbulent time-dependent backgrounds like in flames). This video is made to introduce users to setting up the iStar to acquire image pairs such as these in Fast Dual Frame Mode (also known as PIV mode) through a hands-on demonstration and explores how to minimise the gap in time between the pair of images.
