全息三维显示具有呈现包含真实物体所有特征的三维场景的能力，这对信息的数据量和分辨率提出了极高的要求。体全息术可以为高分辨率三维显示提供大容量数据存储和基于三维布拉格光栅的实现方式。提出体全息三维显示方法，通过计算全息算法得到三维物体的全视差相息图，由相位型空间光调制器对物光波进行波前编码，利用体全息光栅的角度选择特性在光致聚合物的同一全息图基元中复用多幅全息图。在参考光照射下，可以重建出多角度的三维场景，扩充了三维显示的空间带宽积。

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.
