Abstract

PURPOSE:To obtain a hologram copy faithful to an original plate, by superposing a hologram original plate on a hologram material, scanning the backside of the original plate laser beams to transfer it, and uniformly distributing irradiation quantity of laser beams. CONSTITUTION:The photosensitive layer 2 of a hologram original plate 1 having interference fringes formed is overlaid on the emulsion layer 4 of a hologram material plate 3, and the backside of the plate 1 is scanned with laser beams emitted from a laser beam source 12 through a collimeter by moving a plate- placing stand 14 in the X-Y directions as shown in the figure to transfer the interference fringes to the material 3. All the surface of the original 1 is irradiated thus uniformly with the same laser beams to execute transfer faithful to the original 1.
