Abstract

Phase unwrapping remains a challenging problem in optical interferometry. In this paper we only deal with noisy phase maps. The noise is removed by a windowed Fourier transform and then the sequential line scanning method is adopted for phase unwrapping. This simple approach is verified to be effective.
