扫描电流在高倍率扫描成象时,因信噪比恶化,一些高分辨率信息会被淹没.本文介绍用数字图象处理方法,恢复,揭示和测量这些信息的方法.
Scanning current At high magnification, some high-resolution information is submerged due to deteriorating signal-to-noise ratio.This paper presents a method to recover, reveal and measure this information by using digital image processing method.
