Abstract:An improved phase unwrapping method for cellular automata is proposed. It revises the four neighborhood of the original method to the nearest neighborhood, begins from the boundary of the interferogram to iterate, eliminates the phase fringes one by one to achieve the purpose of phase unwrapping.The experiments by using the simulated and real interferograms are made. The result shows that this method can decrease the original iterative times, reduce the occupancy rate of the memory and improve the accuracy of the phase unwrapping.
