Applications of a 1-Mfps video camera to water surface phenomena

A 1 M fps video camera was applied to the observation of drop impacts onto water surfaces. It captured the detailed mechanism of sheet ejection from the contact region between the drop and the water surface, the small droplets separated from the ejected sheet and bubble entrapment by a drop impacting onto a water surface. The 103 consecutive images are enough to form a short movie which is suitable for dynamic recognition.
