Abstract

　記録光（Ｓ）および参照光（Ｒ）を同一の対物レンズ（１３）を通して記録媒体（Ｂ）に照射することによりホログラムを記録するホログラム記録装置（Ａ１）であって、光源（１）からの光を記録光（Ｓ）と参照光（Ｒ）に分割する光分割手段（３）と、光分割手段（３）にて分割した記録光（Ｓ）および参照光（Ｒ）を同心状の光となるように複合させ、これらの光を対物レンズ（１３）へと進行させる光複合手段（１１）と、光分割手段（３）と光複合手段（１１）との間で記録光（Ｓ）および参照光（Ｒ）の光路上に位置する第１および第２のレンズ（５，９）と、第１のレンズ（５）を透過した記録光（Ｓ）を絞る第１のアパーチャ（６）と、第２のレンズ（９）を透過した参照光（Ｒ）を絞る第２のアパーチャ（１０）とを備え、第１および第２のレンズ（５，９）は、光学倍率が異なる。
