Fast Fourier Transform is a kind of methods of image processing, which is used in this paper to analyze evolution of patterns observed in dielectric barrier discharge in air/argon. It is found that a new type of pattern named asymmetric hexagon pattern is a kind of superlattice pattern by analyzing the spatial Fourier spectrum. The evolution of the pattern with voltage increasing is not exactly the...
The characteristic of square superlattice pattern is analyzed by the methods of image processing and image analyzing in dielectric barrier discharge system. The square superlattice pattern consists of large and small spots square sublattice structures. Various square superlattice patterns are performed and investigated. The D/d (the ratio of large spot's diameter to the small ones) and the DeltaG...
Time-varying light emission signals, obtained in patterned dielectric barrier discharge, are processed by combining wavelet technique. For conventional one, it can be only presented the correlation trend between the two signals, while the modified correlation analysis can locate the correlated time exactly. Based on this, the probability density functions of correlation peak label number and correlation...
Various potential tunable plasma photonic crystals have been generated by self-organization in atmospheric dielectric barrier discharge with two liquid electrodes. These periodic plasma column lattices can be modulated both in space and time, which are promising for flexible electromagnetic wave controller or optional optical switch. A special square lattice with a base is obtained for the first time,...
