| Outline of Final Research Achievements |
We are developing the fabrication technology of hologram optical elements which is possible about the reconstruction of the true three-dimensional image. In the holography technology, a computer hologram is obtained. Using a laser lithography system, the pattern of the computed interference fringe is exposed directly on the photomask substrate. We are able to fabricate holograms by exposing a computed fringe pattern by the lithography system and etching to the chromium thin film after developing of photoresist. For wide view area, we used a tiling system of holograms with several meters. By the technique of the heat mode lithography, the pixel pattern of the sub-wavelength was exposed on the photoresist substrate. Based on the interference fringe pattern of the 800 nm pixel pitch, using the reduction exposure technique, we fabricated a hologram of the pixel pitch of the submicron like 320 nm with 80 degree of wide viewing angle.
