Determination of droplet morphology by laser reflection interferometry.
A reflection-interference technique is developed that produces interference fringes by light beams reflected from a droplet surface. The instantaneous size and profile of a sessile droplet can be evaluated from the height and width of the fringe patterns. The method can also determine the contact angle between the droplet and the substrate.
