Abstract

Spatiotemporal patterns are obtained in gas discharge with increasing the voltage with the evolvement as following: random spots, quasihexagonal pattern, hexagonal pattern with large spot, hexagonal pattern with small spot, white-eye pattern, and chaos state. The structures of patterns are studied by analyzing the spatial correlation functions, Fourier spectrum and angular spectral distributions of patterns after the image processing to the images of patterns. Furthermore, the mechanism of the pattern formation is investigated, which indicates that hexagonal patterns both large and small spot are selected by the single mode, while the white-eye pattern results from a three wave resonance.
