原子束计算全息技术的原理与实现

The theory and realization of atomic beam CGH

提出用计算全息技术来实现原子束全息成像 ,降低了原子束全息的实现难度 .首先论述了原子束的波动性质以及如何形成相干性能良好的准单色原子波包 ,然后讨论了原子束计算全息片的设计步骤 ,并给出了制作完成的SiN薄膜计算全息片 。

The realization of atom-beam holography by computer generated hologram have been presented in this paper, which can decrease the difficulty of the atom holography. Firstly the wave nature and cooling mechanism of atoms are analyzed, then the design process and a facture of the atomic SiN film hologram is shown, and finally we present a theoretical plan and the picture of an experiment system.
