| Abstract(in English) | Spatial quadrature amplitude modulation (SQAM) signal whose amplitude and phase are individually modulated to multi-level have been expected to be used for improvement of recording capacity of holographic memory. We have proposed two exposure method (TEM) in which the two holograms for different phase modulated signal is multiplex recorded in the same position and it synthesize the hologram for SQAM signal. In this report, we design new phase pages for TEM by investigating the holographic distribution formed in the memory and show it is possible to suppress the amount of monomer consumed wastefully for the recording SQAM signal by using the new phase pages. |
