The Fresnel zone plate scanning holography is applied in the imaging through highly scattering media. The background noise of the reconstructed image is resulted from the nonnegative coded function. A method of constructing composite hologram for reducing the background noise is proposed. The reconstructions with good-quality signal-to-noise ratio (SNR) and contrast ratio are obtained in experiments using this method. The system point spread function (PSF) is designed to be similar to the Dirac delta function. The experimental results and the theoretical calculation of the PSF are in accordance. The experiments on absorbers embedded in the intralipid solution with concentration of 1% and depth of 1.7 cm are implemented. The results demonstrate that the reconstructions of the metal ring with diameter of 6.0 mm and the metal wire with diameter of 0.4 mm are clear. The reconstruction of the black plastic ball with diameter of 2.5 mm is also satisfied.
