Different coding and quantization techniques in digital phase holography are considered. Characteristics of the methods are discussed with the help of a model of digital phase holography. The parameters diffraction efficiency and signal to noise ratio of the calculated hologram structures are investigated. The described methods are applied to calculate various examples of array illuminators.
