Understanding the evaporation behavior of droplets on a flat substrate is very important for applications of many areas. In order to obtain quantitative three-dimensional imaging of droplet evaporation process, the dynamic digital holography has been employed. The off-axis holograms are recorded by a camera and the object waves are numerical reconstructed. The method can simultaneously provide an amplitude-contrast image and a quantitative phase-contrast image. The theory of digital holography is introduced and the experiment of water droplet evaporation is presented.
