The full-parallax dynamical holographic display: A pure-phase-modulated holographic stereograms approach

A full-parallax dynamical holographic display using pure phase-modulated hologram method based on LCoS is presented, and the full-parallax holographic stereogram is generated. The spectrums of holographic elements on the holographic stereogram plane are obtained from perspective images of objects. The pure-phase-modulated holographic element is proposed to eliminate the conjugate images. An optically reconstructed experiment using phase only SLM is implemented. The experimental results show that 3D object can be constructed successfully with the proposed method.
