Abstract

In this paper, a new method of 3-D data cube based on virtual holographic storage is presented. Firstly, the data information is encoded in the form of 3-D data cube with a certain algorithm, in which the interval along coordinates between every data is d. Using the plane-scanning method, the 3-D cube can be described as a assembly of slices which are parallel planes along the coordinates at an interval of d. The dot on the slice represents a bit. The bright one means "1", while the dark one means "0". Secondly, a hologram of the 3-D cube is obtained by computer with virtual optics technology. All the information of a 3-D cube can be described by a 2-D hologram. At last, the hologram is inputted in the SLM, and recorded in the recording material by intersecting two coherent laser beams. When the 3-D data is exported, a reference light illuminates the hologram, and a CCD is used to get the object image which is a hologram of the 3-D data. Then the 3-D data is computed with virtual optical technology. Compared with 2-D data page storage, the 3-D data cube storage has outstanding performance in larger capacity of data storage and higher security of data.
