diffraction lens meaning in English
衍射透镜
衍射线透镜
Examples
- Now , since the aperture can only be inserted in the one fixed plane it follows that the first image should be formed in this plane and the diffraction lens focused on to it
现在，由于孔可以仅仅被嵌入所属的一个指定的平面，第一成像就应该出现在这个平面并且衍射透镜聚焦在其上。 - In addition to the rotation associated with the reduction in the strength of the diffraction lens there can also be an inversion between the diffraction pattern and the corresponding micrograph
除了通过衍射透镜磁力缩减取得的旋转，还可以有一种衍射模型和对应的显微图之间的倒置。 - As mentioned above , to image the diffraction pattern it is necessary to reduce the power of the diffraction lens by altering the current through the lens coils from the value used to form an enlarged image of the first image
如上所言，要成像衍射模型就必须缩减衍射透镜的能量，通过改变从已有形态到形成第一映像的放大映像过程中穿过透镜圈的能量实现。 - An inverted image is formed in the first image plane and the three subsequent lenses in the namely the diffraction lens , the intermediate lens and the projector lens are used either to magnify this image or to magnify the diffraction pattern
在第一映象平面出现一个倒的图象，随后的第三透镜也就是衍射透镜，中间的透镜和投影透镜被用来放大图象或者放大衍射模式。 - This is achieved experimentally by focusing the selector aperture on the final screen using the diffraction lens , which is most accurately done after removing the objective aperture , and then ( after replacing the objective aperture ) focusing the specimen using the objective lens only
这已经通过使用衍射透镜在最终屏幕上聚焦选择孔实验性的完成，此方法多数能在移动目标孔后准确完成，然后（重置目标孔后）仅通过目标透镜聚焦样本。
