Scientists put forward a simple new way of counting microscopic particles in optical materials. A laser beam passing through such a material splits and forms a pattern of numerous bright spots on a projection screen. The researchers found that the number of these spots corresponds to the number of particles in the material. This finding allows to determine the material structure without resorting to microscopy.
