A recording device for holographic 3D is provided, the device including: a photorefractive crystal (3), a micro lens array (4). The micro lens array(4) includes an array surface and side, and is arranged on the optical path of the photographed object (100) to the photorefractive crystal (3), the first light (201) diffusely reflected by the photographed object (100) passes through the array surface of the micro lens array (4), and forms the second light (202) emitting to the photorefractive crystal (3); the photorefractive crystal (3) is used for receiving the reference light (200) and the second light (202) emitted by the micro lens array (4) respectively, and storing the interference fringes formed by the reference light (200) and the second light (202); the first light (201) and the reference light (200)are coherent light. |
