Holographic 3D Recording Device, Reproducing Device and Display Apparatus

摘要

A holographic 3D recording device includes: a photorefractive crystal and a microlens array. The microlens array includes an array face and a side face. The microlens array is provided in a light path from an object to be photographed to the photorefractive crystal such that first light of object emitted through a diffuse reflection of the object to be photographed passes through the array face of the microlens array and becomes second light of object that is emitted to the photorefractive crystal. The photorefractive crystal is configured to receive the second light of object emitted by the microlens array and reference light, respectively, and save therein an interference fringe formed by the reference light and the second light of object. The first light of object and the reference light are coherent light.
