Abstract

The shear in an interferometer system depends not only on the type of interferometer and its adjustment but also on how the interferometer is used. It is the important parameter that enters into measurements of spatial coherence, from which such quantities as stellar diameters can be derived, and of wavefronts by common-path interferometry. In association with the tilt, the shear determines where the fringes are localized, and its variation can give a scan of this localization.
