Abstract

Multiaperture speckle shear interferometry exhibits sensitivity to in-plane displacement components. The response of the interferometer to in-plane displacement, however, depends on the location of the shear element on an aperture in front of the imaging lens. Two configurations with three apertures, with the shear element positioned at two different locations, are examined theoretically and experimentally.
