AI Technical Summary
Existing holographic recording media have insufficient optical recording properties, especially thermal stability, in the red, green, and blue regions, making it difficult to maintain stability in high-temperature environments.
A holographic recording medium comprising a polymer matrix, photoreactive monomers, and a photoinitiator system is employed. A diffraction grating is formed by modulating the refractive index of the photopolymer layer. Optical recording is performed in the red, green, and blue regions using specific photosensitive dyes. The polymer matrix is rapidly crosslinked at room temperature through a hydrosilylation reaction, thereby enhancing the stability of the material.
It achieves optical recording characteristics in the red, green, and blue regions while maintaining high-temperature stability, ensuring the reliability of the holographic recording medium and the reproduction of optical information in high-temperature environments.
