3d holography device and method implemented

The present invention discloses an apparatus and method for holographic 3D implemented, the apparatus comprising recording means and display means, said recording apparatus comprising: laser generation means for emitting laser light; beam splitting unit for receiving the laser beam generating means emits the laser beam and the laser beam is directed to form a reference beam and the object light of the subject; photorefractive crystal, for receiving the object are photographed object from the reference light from said beam splitting means light form a holographic 3D image; rotation unit, the photorefractive crystal connection for synchronous rotation of the photorefractive crystal at each new recording a holographic 3D image. When displayed, the reproduction light path by rotating the photorefractive crystal are reproduced different holographic 3D image can be realized. The present invention and the hologram recording 3D photorefractive crystal display can achieve a plurality of recording holographic images and 3D display, recording and display very quickly and easily, and can achieve dynamic holographic 3D display optical path of rotation.
