HOLOGRAPHIC LIGHT GUIDE |
摘要 |
A method of making a holographic light guide comprising, in sequence, a substrate, a light guiding layer and a holographic recording layer that partially replaces the light guiding layer is disclosed. The substrate is made of a first bismuth sillenite group substance. The light guiding layer is made of a second bismuth sillenite group substance that has a higher refractive index than the first bismuth sillenite group substance and absorbs little of the light being guided. The holographic recording layer is made of a third bismuth sillenite group substance that has a higher refractive index than the first bismuth sillenite group substance and has a degree of photosensitivity. |
