Abstract
Filtering off noise form fringe patterns is important for processing and analysis of interferometric fringe patterns. Spin filtering proposed by the author has been proven to be effective in filtering off noise without blurring and distortion to the fringe patterns with small fringe curvature. But spin filters still have problems for the fringe patterns with large fringe curvature. In this paper we develop a new spin filtering with curve windows to be suitable for all kinds of fringe patterns regardless of fringe curvature. The curve windows in the filtering coincide with the local fringe contours of fringe gray levels. The experimental result show that the new spin filtering provides the optimal results in both filtering off noise and remaining fringe feature.
