| titleOfInvention | Optical device for image enlargement / reduction, method of manufacturing the same, image enlargement / display device, and image reduction / reading device |
| abstract | (57) [Problem] To provide a thin image enlargement / reduction optical device that can easily enlarge the entire image and the pixel size itself by a simple manufacturing method without using a conventional projection method. SOLUTION: Light emitted according to a display image on a display 8 enters a high refractive index region 5 from a reduction surface 3 side. Of the incident light, the light satisfying the condition of total reflection at the interface with the low refractive index region 6 propagates toward the enlarged surface 4 while repeating total reflection in the high refractive index region 5. Here, since the high-refractive-index region 5 has a larger cross-sectional area on the enlarged surface 4 side than a reduced sectional area 3 side, pixel information incident from the reduced surface 3 side is enlarged on the enlarged surface 4 side. And is enlarged and displayed on the enlarged display surface 9. That is, the entire image and the pixel size itself are enlarged. At this time, by using a polymer material as the material of the plate 2, the refractive index distribution of the high refractive index region 5 can be easily formed using light irradiation, and the thin, lightweight, and low-cost optical device for image enlargement / reduction 1 is used. Can be provided. |
