Abstract
In this paper we first describe two existing schemes to construct binary amplitude or phase holograms for arbitrary complex amplitude modulation in the +1 order diffracted beam. We then propose another binarization scheme for complex amplitude modulation that uses a combination of fixed as well as statistically dependent threshold values for binarization. We perform a numerical investigation to compare the accuracy of the three binarization schemes to incorporate spatial intensity modulation in a laser beam and observe that the proposed scheme offers significant relative advantage in terms of aliasing. We present experimental results that supports the above observations.
