Abstract
In this paper, we investigate the orthogonal reconstruction in orthogonal linear polarization holography. Orthogonal reproduction means that the polarization of the diffracted light is orthogonal to the polarization of the recorded signal light. Based on the newly developed polarization holography theory with the tensor method, we analyzed the prerequisite for orthogonal reconstruction and verified it experimentally by constructing an experimental platform. Through quantitative analysis and multiple experiments, the power of the diffracted light was related to the interference angle between the recorded signal light and reference light during the recording process when the diffracted light was subjected to orthogonal reconstruction. The experimental results are in good agreement with the results obtained via theoretical analysis. Thus, our knowledge related to polarization holography may be improved through orthogonal reconstruction.

Abstract The optical response of polarization sensitive materials is studied on the basis of a model in which the materials consist of rod molecules that are oriented in random directions. The photoinduced change of the dielectric tensor is expressed as a function of the electric field in a general form. Using this expression, we derive the vectorial coupled wave equations in volume polarization holograms. We discuss the basic properties of polarization holograms.

Holographic data storage system (HDSS) has been a good candidate for a volumetric recording technology, due to their large storage capacities and high transfer rates, and have been researched for tens of years after the principle of holography was first proposed. However, these systems, called conventional 2-axis holography, still have essential issues for commercialization of products. Collinear HDSS, in which the information and reference beams are modulated co-axially by the same spatial light modulator (SLM), as a new read/write method for HDSS are very promising. With this unique configuration, the optical pickup can be designed as small as DVDs, and can be placed on one side of the recording media (disc). In the disc structure, the preformatted reflective layer is used for the focus/tracking servo and reading address information, and a dichroic mirror layer is used for detecting holographic recording information without interfering with the preformatted information. A 2-dimensional digital page data format is used and the shift-multiplexing method is employed to increase recording density. As servo technologies are being introduced to control the objective lens to be maintained precisely to the disc in the recording and reconstructing process, a vibration isolator is no longer necessary. Collinear holography can produce a small, practical HDSS more easily than conventional 2-axis holography. In this paper, we introduced the principle of the collinear holography and its media structure of disc. Some results of experimental and theoretical studies suggest that it is a very effective method. We also discussed some methods to increase the recording density and data transfer rates of collinear holography.
