The methods of generating the cross derivatives of in-plane displacements by lateral shear interferometry and their subsequent addition are presented. Two approaches are introduced: (1) spatial filtering of composed diffraction structures and (2) moire superimposition of conjugate-type lateral shear interferograms. Experimental corroboration of the principle is presented.
