A method for recording a reflection type volume hologram of a 3-dimensional object and additional information, said method comprising: recording a hologram of said 3-dimensional object in a reflection type volume hologram original plate; placing a hologram photosensitive material at a distance from said reflection type volume hologram original plate, wherein the reflection type volume hologram original plate has a transparent plate with a predetermined thickness laminated thereon and the hologram photosensitive material is laminated on the transparent plate; placing a transparent sheet at a side of said hologram photosensitive material remote from said reflection type volume hologram original plate, said transparent sheet having a plane additional information pattern recorded thereon; and recording a reflection type volume hologram in said hologram photosensitive material by applying duplicating illuminating light for duplicating said reflection type volume hologram original plate from said transparent sheet side, wherein the duplicating illumination light passes through said transparent sheet and said plane additional information pattern and thereafter through said hologram photosensitive material and the transparent plate and is incident on the reflection type volume hologram original plate, so that diffracted light from said reflection type volume hologram original plate and said duplicating illuminating light interfere with each other in said hologram photosensitive material, thereby recording a reflection type volume hologram of an image of the 3-dimensional object reconstructed from the reflection type volume hologram original plate and simultaneously recording said plane additional information pattern holographically in said hologram photosensitive material, thereby when said reflection type volume hologram is illuminated with white illumination light the following images are reconstructed simultaneously: an image (I', I") of said 3-dimensional object in a vicinity of a hologram plane of the reflection type volume hologram; an image (A') of the plane additional information pattern in the hologram plane; and an image (B') of the plane additional information pattern in front of or behind the hologram plane. recording a hologram of said 3-dimensional object in a reflection type volume hologram original plate; placing a hologram photosensitive material at a distance from said reflection type volume hologram original plate, wherein the reflection type volume hologram original plate has a transparent plate with a predetermined thickness laminated thereon and the hologram photosensitive material is laminated on the transparent plate; placing a transparent sheet at a side of said hologram photosensitive material remote from said reflection type volume hologram original plate, said transparent sheet having a plane additional information pattern recorded thereon; and recording a reflection type volume hologram in said hologram photosensitive material by applying duplicating illuminating light for duplicating said reflection type volume hologram original plate from said transparent sheet side, wherein the duplicating illumination light passes through said transparent sheet and said plane additional information pattern and thereafter through said hologram photosensitive material and the transparent plate and is incident on the reflection type volume hologram original plate, so that diffracted light from said reflection type volume hologram original plate and said duplicating illuminating light interfere with each other in said hologram photosensitive material, thereby recording a reflection type volume hologram of an image of the 3-dimensional object reconstructed from the reflection type volume hologram original plate and simultaneously recording said plane additional information pattern holographically in said hologram photosensitive material, thereby when said reflection type volume hologram is illuminated with white illumination light the following images are reconstructed simultaneously: an image (I', I") of said 3-dimensional object in a vicinity of a hologram plane of the reflection type volume hologram; an image (A') of the plane additional information pattern in the hologram plane; and an image (B') of the plane additional information pattern in front of or behind the hologram plane. an image (I', I") of said 3-dimensional object in a vicinity of a hologram plane of the reflection type volume hologram; an image (A') of the plane additional information pattern in the hologram plane; and an image (B') of the plane additional information pattern in front of or behind the hologram plane.
