Abstract

Sampled images of two-dimensional objects are obtained from holograms recorded by using achromatic-fringe interferometer arrangements in which the beam splitting is achieved by a hologram of a random phase-sampling pattern. The use of monochromatic but spatially incoherent source suppresses both speckle and moiré without reducing contrast of the fringes at the hologram plane. The principle was analyzed in the case of Fourier holograms and verified experimentally.
