Shifting of localization planes in optical testing: Application to a shearing interferometer

Mostrar todas las versiones(2)

An amplitude-division two-beam interferometer illuminated by a quasi-monochromatic, spatially incoherent, and periodic source yields multiple localization planes of interference fringes. If a thick transmission sample with a few localized phase disturbances in various layers is placed in the interfe...
