Large real-time holographic 3D displays: enabling components and results

A holographic 3D display with 300  mm×200  mm active area was built. The display includes a spatial light modulator that modulates amplitude and phase of light and thus enables holographic reconstruction with high efficiency. Furthermore, holographic optical elements in photopolymer films and laser light sources are used. The requirements on these optical components are discussed. Photographs taken at the display demonstrate that a 3D scene is reconstructed in depth, thus enabling selective accommodation of the observer's eye lenses and natural depth perception. The results demonstrate the advantages of SeeReal's holographic 3D display solution.
