Paper Abstract

The recursive filtering algorithm, a simpler method of filtering for electronic speckle pattern interferometry (ESPI) images, is presented and studied in the paper. In pace with the new method, the applied software is developed specially. By experimental demonstration, it shows that the technique is the most effective and speedy method for the filtering of ESPI fringe patterns so far. Comparing with the images before and after filtering, we can see these advantages of the novel technique clearly.
