Abstract

Off-axis holograms recorded with a CCD camera are numerically reconstructed in amplitude by calculating through the Fresnel-Kirchhoff integral. A phase-shifting Mach-Zehnder interferometer is used for recording four- quadrature phase-shifted off-axis holograms. The basic principle of this technique and its experimental verification are described. We show that the application of this algorithm allows for the suppression of the zero order of diffraction and of the twin image and that the contrast of the reconstructed images can be further enhanced by digital compensation of the aberrations introduced by the holographic recording system.
