A hologram is a 3D image technology that can represent both intensity and phase of light and provide people with stereoscopic and accommodation effect. Currently, various researches on development of holographic display are in progress and one of the key issues is complex hologram representation which modulates both amplitude and phase. The ideal complex hologram is free from DC and twin problems that hinder hologram image observation. However, currently available spatial light modulators, which are widely used display devices in holographic displays, can only modulate either amplitude or phase. In this paper, we propose a full complex hologram representation method based on DOE phase mask. It will be useful for amplitude type SLM based holographic display.
