It is then necessary to generate only the parts of the hologram that are relevant to the viewer's position and direction of gaze, greatly reducing the amount of processing required.

这样，只需生成与观众位置和目光方向有关的全息图即可，大大降低了所需运算量。

Analyzing the difference of atom hologram and optical hologram, we point out that only the laser cooling atoms can satisfy the coherent and diffract conditions required by the hologram technology.

分析讨论了原子全息与光学全息的区别，指出只有经激光冷却的原子束才满足全息技术所要求的相干条件和衍射条件。

A phase hologram not only has relief modulation but also has refractory index modulation, both modulation will affect the diffraction property of the phase hologram.

位相全息图一般既有浮雕调制又有折射率调制，它们都会对衍射特性产生影响。
