Title: HOLOGRAM RECORDING STRUCTURE, OPTICAL DEVICE, AND MANUFACTURING METHOD
Abstract:
A hologram recording structure has a hologram recording medium on a transparent substrate. The hologram recording medium has, in sequence from the transparent substrate side, a stress-absorbing layer, a base film, a hologram photosensitive material, and a cover film, each contacting the adjacent layers. The stress-absorbing layer has a lower Young's modulus than the transparent substrate and the base film.
