透射电子显微镜侧插式CCD相机数字图片放大倍数的解析

Magnification Analysis of Digital Image of Side-line Charge Coupled Device Camera of Transmission Electron Microscope

针对数字化透射电子显微镜与传统透射电子显微镜在观察记录系统上存在的差异,通过比较分析数字化透射电子显微镜侧插式电荷耦合器件(CCD)相机采集的图像、操作界面View视窗观察到的图像与电镜示数放大倍数之间的差异,详细地分析了数字化透射电子显微镜侧插式CCD相机采集的数字图片的放大倍数发生变化的原因.可以帮助应用电镜的广大教师及科研工作者更加快速、直观地掌握数字图片确切的放大倍数,更有利于结果的分析.

According to the differences between digital transmission electron microscopy with conventional transmission electron microscope in observing and recording a system,we analysed the reasons for the change of magnification of the picture collected by digital transmission electron microscope through the comparison of the differences between the images collected by digital transmission electron microscopy with side-line charge coupled device（ CCD） cameras,images observed by the interface view window and electron microscope in magnification. This study enables the teachers and researchers to grasp the exact magnification digital pictures more quickly and intuitively to analyze the results.
