Three-Dimensional Display Based on Volume Holography
Holographic three-dimensional (3D) display can present a 3D scene with all characteristics of real-world objects. Large data recording and high resolution reconstruction are the challenges for holographic display. Volume holography is capable of recording and retrieving large capacity data based on 3D Bragg grating for high resolution 3D display. 3D display based on volume holography is studied. Full- parallax kinoforms of the 3D objects are acquired by the algorithm of computer generated holography. The wavefront information is encoded by a phaseonly spatial light modulator. Multiple holograms can be imposed into the same holographic element(hogel) in the volume holographic polymer by using angle multiplexing. The 3D object are reconstructed by illuminating with the reference beam. The space-bandwidth product of the system is expanded.
