Speckle interferometry with an imaging grating interferometer

Abstract

A new speckle interferometric technique utilizing an imaging grating interferometer is introduced. Because the conventional dual aperture is replaced with a set of holographic gratings, the technique offers higher sensitivity and efficiency than existing techniques, and it produces interferograms with an image quality compatible with that obtained by holographic techniques.
