Speckle photography and double aperture speckle interferometry using both sides of a suitably designed hololens imaging configuration

Abstract

In the present work, both sides of a suitably designed hololens imaging configuration have been used in laser speckle photography and double aperture speckle interferometry. A speckle photographic technique has been used to measure in-plane displacement, and a double aperture speckle interferometric technique has been used to measure in-plane displacement component.
