Fringe sharpening and information coupling in speckle shear interferometry

Not Accessible

Your library or personal account may give you access

Abstract

Fringe sharpening is required to obtain a higher accuracy of measurement. Nonlinear recording and consequently filtering at the higher-order halos for image formation give sharpened fringes in the image. Furthermore, if the apertures during recording are properly arranged, cross-frequency orders appear, which when used for filtering provide moiré fringes of higher contrast due to intercoupling.
