We have invented (SDAM) to measure the fine wetting details of water-repellent surfaces. SDAM does not require a direct line of sight of the contact area, allowing measurement of uneven surfaces such as fabrics or biological surfaces. It is extremely sensitive and 1000 times more precise than the previous wetting characterization methods. In addition, it can detect wetting properties of microscopic functional features that were previously very difficult to measure. The method has been applied in the characterization of novel materials, including , , and various .
