[10p-W331-11] Improvement of Reconstructed Image Quality on Coaxial Holographic Data Storage in Simultaneous Recording/Reading Method by Modulating Input Data

Yuki Yoshimitsu¹, 〇Yusuke Saita¹, Takanori Nomura¹ (1.Wakayama Univ.)

Keywords:Holographic data storage, Computer-generated hologram, Optical memory

Simultaneous recording and reading of multiple data pages by using a computer-generated hologram pattern designed to divide each lightwave at the recording medium plane has been proposed. In this presentation, improvement of the problem that the quality of reconstructed images degrades in the proposed method is presented.
