摘要: The distance between two spots in a complex hexagon superlattice pattern, whose cell is composed of closing the center and six vertexes hexagon, studied by image processing technology. At first, binary used to determine coordinates all which consists lot with different lightness size. Then spatial correlation function calculate probability density spots. It presents several peaks. first one corresponds second side length cell. found that about 2.2 times
