Abstract: We present a new method to manage the depth of focus in holograms numerical reconstructions through an adaptive deformation of the digital holograms. We demonstrate
that this technique can be applied both to Fourier and Fresnel holograms. The experimental results, in agreement with the theoretical model, are shown and commented for both these configurations.
