To characterize the shape, the quality, and the roughness of microshells, digital holographic microscopy technology is used because it offers an appropriate ability to these studies. It captures holograms to reconstruct a double image, one for the intensity and another one for the phase. Using rotation axis, bump counting for the complete microshell surface is possible with a very high speed. Using image stitching and three-dimensional surface rebuilding software, mapping can be done in a few minutes. Each bump can then be characterized on the map by its position, diameter, and height.
