Based on printing techniques, its sought to substitute each hologram pixel for an arrangement of certain size, trying to simulate the original value with a density of binary values. In this way a direct relationship between the arrangement size and the number of values that can be simulated is obtained.
Finding the appropriate arrangement size, its important to establish which shape or pattern will be used. In this theme some variants are proposed, however we highlight the random patterns, showing very interesting properties. Because of this, a small study is carried about propagation of randomness and its effects on the reconstructed field.
