Abstract

　ホログラム再生装置は、再生時における参照光（Ｒ’）を、ホログラム記録媒体（Ｈ）に対して主たる入射方向をなすメインビーム（Ｒ０）と、これに対して空間的にずれた入射方向をなすサブビーム（Ｒ１，Ｒ２）とに分割する再生参照光分割手段（１１）と、メインビーム（Ｒ０）およびサブビーム（Ｒ１，Ｒ２）の入射方向を変化させる入射方向可変照射手段（２０）と、サブビーム（Ｒ１，Ｒ２）に応じて生じた再生光（Ｐ）の一部をサーボ光（Ｐ１，Ｐ２）として検出するサーボ光検出手段（５０）と、メインビーム（Ｒ０）に応じて生じた再生光（Ｐ）の主部（Ｐ０）を受光する受光手段（３２）と、サーボ光（Ｐ１，Ｐ２）の検出結果に基づき、参照光の光強度を一定とした場合に受光手段（３２）の受光量が所定レベル以上となる入射方向にメインビーム（Ｒ０）を合わせた上で受光手段（３２）により得られた像を再生する再生手段（６０）とを有している。
