原始资料的全息点存储

Holographic Storage of Original Documents

用无透镜傅里叶变换全息图对文献资料直接进行存储,既保留了傅里叶变换全息图的各种优点,又省去对原始资料作微缩胶片的麻烦手续,记录系统十分简便,并可用细激光束照明再现。

A new method using lensless Fourier transformation holograms to store documents directly is proposed. It not only has all kinds of the advantages of Fourier transformation holograms but also dispenses with the difficult step of microphotographing the original documents . Recording system is very simple and thin beams can be used in the reconstruction .
