Abstract

A new approach to phase unwrapping is proposed which uses knowledge about the band limits of the unwrapped phase. A phase unwrapping algorithm is demonstrated which incorporates such knowledge: cases where it unwraps phase correctly where standard phase unwrapping algorithms fail, and cases where it fails and standard algorithms unwrap correctly are demonstrated. It is argued that a hybrid algorithm combining both the standard and new approach might be both robust and practical.
