| Outline of Final Research Achievements |
Recently, researches of holographic storage systems and very large scale integrations using a holographic memory technology or optically reconfigurable gate arrays are being done. Under such researches, although the bandwidth of a reading operation can be improved by increasing the resolutions of its image sensors, the improvement is not easy because the spot size has already reached the diffraction limitation of light. Therefore, in this research, in order to extract some bit information from a single spot, we have developed a polarization holographic storage system which can read the polarization angle from a spot generated from a holographic memory.
