Title: Picture magnifying/reducing optical device, its manufacturing method, picture magnifying display and picture reducing/reading device
Inventor: FUTAMURA YOSHIROU
IPC: H04N5/66
Filed: 2000-08-02
Abstract: PROBLEM TO BE SOLVED: To provide a thin type picture magnifying/reducing optical device by which the magnification of the whole picture and a pixel size itself is easily manufactured with a simple manufacturing method without using a conventional projection system. SOLUTION: Light emitted in accordance with a displaying picture of a display 8 is made incident on a high refractive index region 5 from a reduction surface 3 side. Light which meets a total reflective condition in the boundary with a low refractive index region 6 of incident light is propagated toward the magnification surface 4 side while repeating total reflection in the high refractive index region 5. Hereupon, since the cross section of the magnification surface 4 side is larger than the cross section of the reduction surface 3 side in the high refractive index region 5, pixel information made incident from the reduction surface 3 side is emitted in a shape magnified in the magnification surface 4 side and is magnified and displayed in a magnifying/displaying surface 9. That is, the magnification of the whole picture and the pixel size itself is performed.  In this time, the distribution of the refractive index in the high refractive index region 5 is easily manufactured while utilizing light irradiation by using a high polymer material as a material of a plate 2, and the picture magnifying/reducing optical device 1 which is thin, lightweight and inexpensive is provided.
