Abstract: | New computer-generated holograms using As-Se-S-Ge chalcogenide amorphous film are presented. The chalcogenide film is sensitive to an electron beam and has a high resolution (3000 lines/mm). Utilizing a fine focused electron beam and a high resolution of the amorphous film, full size computer-generated holograms can be directly fabricated without reducing process, and thus a real-time process is possible. Computer-generated holograms with 64 × 64 cells have been experimentally demonstrated in 560 μm × 560 μm hologram size. |
