"In this work the sensitivity vector is analyzed for collimated and divergent illumination for an out-of-plane arrangement. The geometry of the optical setup that we used allowed us to find sensitivity mostly along the pulling direction; the other two components of the sensitivity vector were relatively small. We measured the displacement induced only along the pulling direction. Experimental and theoretical results are presented for the out-of-plane electronic speckle pattern interferometer. The analyzed object was an aluminum plate."
