Paper Abstract

Shearing speckle interferometry using the wedge arrangement yields displacement derivative fringes that are modulated by in-plane displacement fields. In this paper, it is found that using a biprism instead of a wedge suppresses the in-plane displacement modulation effect without affecting the visibility of the displacement derivative fringes.
