Abstract

The speckle that is formed in coherent illumination confuses efforts to record an object's fine details. The confusion is particularly severe in optical metrology and microscopy. In this paper, a scheme using the empirical mode decomposition (EMD) to remove speckles is proposed. This makes it possible to accurately evaluate phases from a fringe pattern illuminated by a coherent light source.
