中文摘要：

实验利用数字全息干涉技术对电极反应过程中溶液浓度变化分布进行测量。运用基于直方图的自适应滤波方法和基于形态学滤波的固液界面提取方法，解决了每更换一次实验数据都要人工识别和更换滤波参数以及手动去除固侧干扰信息的难题，为实现从摄像机实时读取数据、实时处理、测量和观察提供了仿真依据。

英文摘要：

The experiment is to use digital holographic interferometry to observe the solution concentration change distribution at the electrode-solution interface during electrochemical reaction. The auto-filter based on histogram and the electrode-solution interface extraction based on morphological filter were applied to avoid manually selecting the band filter parameters and removing the disturbing solid-side information every time when experiment data changes. The two problems＇ being solved shows that real- timely reading data from camera and real-timely processing, measuring and observing data is possible.
