SEM DIGITIZATION SYSTEM

这个项目是为了评估数字化的性能 11 itachi S-900高分辨率场发射扫描电镜系统。 这个目标 研究的目的是回答以下问题：1）什么是最低限度 数码成像应使用多少像素？ 2)什么程度的 可以实现信噪比的改善？ 3)剂量的 数字图像提供更多有用的信息或增强可视性？ 4)数字图像输出是否优于模拟图像？ 测试 制备样品并选择参数用于比较 分析.

This project is to evaluate the performance of a digitization system for 11itachi S-900 high resolution FESEM. The goal of this study is to answer the following questions: 1) What is the minimum pixel number should be used for digital imaging? 2) What degree of improvement on signal-to-noise ratio can be achieved? 3) Dose the digital image provide more useful information or enhance visibility? 4) Dose the digital image output be better than analog image? Test samples were prepared and parameters were chosen for a comparative analysis.
