HOLOGRAM RECORDING FILM PROVIDED WITH ADDITIVE INFORMATION AND RECORDING METHOD OF THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a hologram recording film with hologram images of additive information patterns, such as characters and images superposedly recorded on a surface having a length from the hologram surface simultaneously with duplication of a subject hologram image in the same volume hologram photosensitive material. SOLUTION: This hologram recording film is simultaneously reconstructably recorded with the additive information B' of a reflection type in superposition of the reconstructed image 1 from the volume hologram 20 and is simultaneously reconstructably recorded with the additive information A' of a transmission type having a mirror image relation with the additive information B' of the reflection type.
