数字全息图由 2D CCD 阵列通过场景反射或散射的波场与相干参考波的叠加来记录。如果将记录的数字全息图馈送到空间光调制器（SLM）并且由参考波照亮，则可以重建整个原始波场。重建的波场包含相位和强度分布，这意味着它是全3D的，表现出深度和视差等效果。因此，数字全息技术的概念是一种很有前景的 3D 电视方法。在我们之前的一部作品中，对 3D 电视的全数字全息方法进行了初步介绍。在这里，我们的一种方法经过实验验证，并研究了其功能和局限性。
A digital hologram is recorded by a 2D CCD array by superposition of the wavefield reflected or scattered from a scene and a coherent reference wave. If the recorded digital hologram is fed to a spatial light modulator (SLM) and this is illuminated by the reference wave, then the whole original wavefield can be reconstructed. The reconstructed wavefield contains phase and intensity distributions, which means it is full 3D, exhibiting such effects as depth and parallax. Therefore, the concept of digital holography is a promising approach to 3D-TV. In one of our previous works the preliminaries of an all-digital-holographic approach to 3D-TV were given. Here one of our approaches is experimentally verified and its capabilities and limitations are investigated.
