PROBLEM TO BE SOLVED: To provide a process by which a multi-image type hologram wherein one 3D image changes over to another depending on a viewing direction can be fabricated in simple construction and a multi-image type hologram fabricated by that process.;SOLUTION: According to the process for the fabrication of the multi-image type hologram wherein one image changes over to another depending on a viewing direction, the area of a hologram recording material is divided into a plurality of sub-areas 1111 to 1113. Objects to be displayed on different images are holo-graphically recorded in the respective sub-areas, using reference light having the same angle of incidence, thereby recording the first-stage hologram 11. Object images O1' to O3' recorded in the respective sub-areas 1111 to 1113 are simultaneously reconstructed from the recorded first-stage hologram 11, so that a second-stage hologram recording material 21 is located near the reconstructed object images O1' to O3' for recording them as a reflection or transmission type volume hologram.;COPYRIGHT: (C)2008,JPO&INPIT
