Water repellency is used in a wide range of applications from daily necessities to industrial products, and plays an important role in controlling wettability.Shape measurment of water droplet on water-repellent surface is one of the indexes for evaluating the level of water-repellent effect and the deterioration of water-repellent function. In this study, we measure changes in the shape of a water droplet on a water-repellent glass slide using digital holography that applies burst imaging.
