Abstract:
Devices and methods for recording and reproducing a holographic 3D image are provided. The devices for recording the holographic 3D image comprising: a laser generation unit for emitting a laser beam; a beam splitter unit configured to receive the laser beam from the laser generation unit and split the laser beam into a reference beam and an object beam directed to an object to be photographed; a photorefractive crystal configured to receive the reference beam from the beam splitter and the object beam diffused from the object to form a holographic 3D image; and a rotation unit configured to rotate the photorefractive crystal once every time one holographic 3D image is recorded. The holographic 3D image can be recorded and reproduced by the rotate the photorefractive crystal in light paths of recording and reproduction light beams, respectively.
