Abstract

This paper proposes a new method for three-dimensional dynamic holographic display that combines computer generated holography (CGH) and holographic stereogram. Theoretically, three-dimensional (3D) dynamic holographic display can be achieved by using CGH alone, however the application of CGH is still limited because large amounts of data processing and complex mathematical calculation of off-axis diffracted light field. A new method combining CGH and stereogram is proposed, since stereogram uses a set of 2D images instead of a 3D object, both the complexity of the calculation and the resolution requirements of spatial light modulator (SLM) is reduced. To prove the feasibility of this method, experiments of making hologram using this method is carried out and the result shows that 3D displaying with a view angle of 28 is achieved.
