  • For the purpose of dealing with low-resolution interferograms acquired by large-diameter interferometer,a method was presented including homogenization and ternary and so on.The acquired interferograms,which couldn't be processed by interferometers,were filtered and the 3-D surfaces were restored.Compared with the traditional Goldstein filter method,the results show that this method enhances the restoration possibility of low resolution interferogram,and paves the way for its latter process.
