Research On The Phase Unwrapping Algorithm Interference In The Information Field

The phase unwrapping technique can reflect the phase information of an image, this is a very broad prospects for the interference image processing technology, then the wrapped phase different, we can choose different phase according to the fact situation of unwrapping algorithm, when the true phase information we want to extract objects, will encounter all sorts of difficulties, such as noise, shadow, fracture and so on negative factors, these will bring great impact on work. Therefore, according to the different needs of the interference pattern, unwrapping method should be relatively.In this paper, for a variety of phase unwrapping algorithm are analyzed, and draw the advantages and disadvantages, and that we can on the phase unwrapping algorithm has a simple and clear understanding, and the methods required to choose according to their advantages and disadvantages. And the classical least squares method of the interference fringe and reference of the laser plasma shock wave interference fringe pattern simulation results.I hope that through this article research phase algorithm solution package to develop a new research ideas, and make the readers understand the main essence of the algorithm, for the future research is the basis of theory and practice.
