Paper Abstract

In this paper, we consider a simple object-independent diffuser for digital holography that is characterized by a constant absolute value of the phase difference between its samples. In order to have desirable characteristics, the distribution of the signs of phase difference of it must be sufficiently randomized. We thus propose an effective algorithm for this purpose. Finally, we show that this diffuser can be used to initialize the phase of an intensity object for successfully calculating its complex amplitude, which is band-limited and at the same time possesses a smooth spectrum, and which fulfills the basic requirement for efficiently encoding it into a hologram and reconstructing it with reduced speckles.
