AI Technical Summary

Technical Problem

In the existing technology, the readout rate of the femtosecond processing fluorescence defect information storage system based on solid materials is low, which cannot meet the practical requirements of high-throughput information transmission.

Method used

By determining the readout parameter set, parallel information is read from N points in the solid material, the number of photons from the fluorescence defects is excited and read, and the information to be read is determined by using a preset mapping relationship. A rotating device is used to adjust the rotation speed to improve the readout rate.

Benefits of technology

This study improved the information readout rate of the solid material fluorescent defect information storage system, achieving a readout rate of 100 M/s while maintaining 99% fidelity.

Abstract

The present disclosure provides a method and system for high-speed information readout based on a fluorescence defect in a solid material, which can be applied in the technical field of optical information storage. The method comprises: determining a readout parameter set, wherein the readout parameter set is configured to perform parallel information reading on N points to be read which are comprised in a solid material, said points have fluorescence defects, and different fluorescence defects correspond to different pieces of information to be read; on the basis of the readout parameter set, exciting the fluorescence defect at each of said N points, and reading the number of photons at each of said N points to obtain at least one piece of fluorescence data, wherein the fluorescence data comprises the number of photons corresponding to each of M points to be read, the number of photons corresponds to the fluorescence defect of the corresponding point to be read, M and N are positive integers, and M is less than or equal to N; and on the basis of the at least one piece of fluorescence data and a preset mapping relationship, obtaining the information to be read stored at each of said N points.
