A method for Chinese character holographic storage and retrieval based on multi-modal photon encoding
By combining multidimensional encoding of Chinese characters with multimodal photon modulation, the shape, speech and semantic features of Chinese characters are mapped into light field signals. This solves the problem of combining semantic information encoding of Chinese characters with holographic storage in existing technologies, realizes high-density storage and efficient retrieval, and improves storage capacity and media lifespan.

AI Technical Summary
Existing holographic storage technology has failed to effectively utilize the three elements of form, sound, and meaning of Chinese characters and photon multimodal modulation for structured mapping, resulting in the failure to combine Chinese character semantic information encoding with holographic storage.
A multidimensional encoding method for Chinese characters is adopted to extract the glyph, phonetic and semantic features of Chinese characters into multidimensional encoding vectors. These vectors are then converted into amplitude, phase and polarization signals of the light field through multimodal photon modulation. The vectors are written using a photopolymer holographic storage medium and then decoded and retrieved using a deep neural network.
It achieves high-density storage and efficient retrieval of Chinese character information, increases the storage capacity of a single holographic data page, extends the lifespan of the storage medium, and improves the recall and recall rates of retrieval.
