    • A method and apparatus for improving quality of a signal reproduced from a holographic storage medium in which a hologram is recorded by interference between a signal beam and a reference beam. The signal-quality improving method includes determining a page crosstalk value, which is caused in a page that is to be reproduced from the holographic storage medium by an adjacent page to the page that is to be reproduced, on the basis of on-pixel crosstalk values caused by a plurality of on-pixels of the adjacent page; and removing the determined page crosstalk value from a reproduced signal of the page that is to be reproduced. Since an interpage crosstalk that occurs when multiplexing recording in the holographic storage medium is calculated, and is removed from a reproduced signal, the quality of the reproduced signal can be improved.
    • 一种用于提高从全息存储介质再现的信号的质量的方法和装置,其中通过信号光束和参考光束之间的干涉来记录全息图。 信号质量改进方法包括:基于像素间串扰来确定在从全息存储介质被相邻页面再现到要被再现的页面的页面中引起的页面串扰值 由相邻页面的多个像素引起的值; 以及从要再现的页面的再现信号中去除确定的页面串扰值。 由于计算在全息存储介质中复用记录时发生的帧间串扰,并且从再现信号中去除,所以可以提高再现信号的质量。

    • A holographic recording/reproducing apparatus that easily controls an incident angle of a reference beam and that is less sensitive to a tilt of a holographic recording medium, the holographic recording/reproducing apparatus including: a light source to emit a light; and an optical system to divide the emitted light into a reference beam and a signal beam, and to provide the reference beam and the signal beam to the holographic recording medium, wherein the optical system provides the signal beam to be incident on an upper surface of the holographic recording medium, and provides the reference beam to be guided along the inside of the holographic recording medium by reflection due to a refraction index difference between the holographic recording medium and the outside of the holographic recording medium.
    • 一种全息记录/再现装置,其易于控制参考光束的入射角,并且对全息记录介质的倾斜不太敏感,全息记录/再现装置包括:发光的光源; 以及用于将发射的光分成参考光束和信号光束并将参考光束和信号光束提供给全息记录介质的光学系统,其中光学系统提供信号光束入射到全息记录介质的上表面 全息记录介质,并且通过由于全息记录介质和全息记录介质的外部之间的折射率差引起的反射,提供将沿着全息记录介质的内部引导的参考光束。
