Abstract
Multiaperture speckle shear interferometry exhibits sensitivity to in- plane displacement components. The response of the interferometer to i n-plane displacement, however, depends on the location of the shear el ement on an aperture in front of the imaging lens. Two configurations with three apertures, with the shear element positioned at two differe nt locations, are examined theoretically and experimentally. (C) 1996 Optical Society of America.
