Holography of Fresnel-Zone-Plate Convolution Without Motion
The holography of Fresnel-zone-plate (FZP) convolution without motion was proposed. The key of the technique is that the uniformly distributed source is used to make the FZP projects superposed on the object. The hologram was obtained by convoluting the FZP intensity-distribution function with the object intensity-distribution function without mechanical motion. The reconstruction of the hologram was obtained by digital correlation. The relationships between the exiting intensity distribution of FZP and the depth of the scattering media were simulated by the method of Monte Carlo. The simulation results demonstrate that the FZP intensity distribution is still maintained when the depth of the scattering media is equal to 5 cm. The imaging experiments on the 0.4 mm-diameter metal at different depth of 1 cm,3 cm and 5 cm were carried out. The experimental results testify that the holography of FZP convolution without motion is possible to be used in imaging of objects embedded in highly scattering medium.
