Abstract

One of the unsolved problems in the well-established field of holographic interferometry is identification of zeroth-order fringes in cases in which the locations of zero displacement are unknown. We offer a simple solution: By making the double-exposure hologram of a white object in full color by using three or more wavelengths, the zeroth-order fringes will be indentified by their white color.
