In the holographic memory, the achievable multiplexing number of holograms and the recording density are inherently restricted by the dynamic range in a medium. To suppress the consumption of dynamic range in a medium, we propose a multiplexing technique using the virtual phase conjugation. In this method, multiple signals that contain data pages are simultaneously recorded into a recording medium by utilizing the property of the beam diffusion with a random diffuser and the wavefront reconstruction of a phase conjugation light. Consequently, this method enables us to reduce the exposure amount for recording data pages. Furthermore, this method keeps the increasing size of optics at minimum by computationally processing the phase conjugate reconstruction of data pages. In our simulation, by observing the refractive index modulation depth in medium in which holograms recorded, we confirm that this method can suppress the consumption of the medium’s dynamic range. In addition, we also confirm that the suppression for the consumption of dynamic range improves the recording capacity in the holographic memory. |
