A De Trailing Algorithm For Scanning Electrochemical Imaging Based On Deconvolution

Scanning electrochemical imaging,as a research tool of electrochemistry,has been applied to every research direction of electrochemistry and applied to other fields.In the process of scanning electrochemical imaging,trailing phenomenon makes the low resolution scanning electrochemical imaging not only causes a lot of sawtooth interference in the edge region of the imaging,but also blurs the whole image,which is extremely unfavorable to the electrochemical analysis.Improving the precision of scanning imaging can effectively reduce the effect of trailing on the electrochemical imaging,but at the same time it also causes a lot of time and cost,which has brought great experimental constraints to the related electrochemical research.Therefore,the aim of this paper is to use a data processing technique to improve the trailing phenomenon in low resolution scanning electrochemistry imaging,and to get better scanning electrochemical imaging with less time and money.Therefore,we first analyse the causes of the trailing phenomenon of scanning electrochemical imaging,then we present a de trailing algorithm for scanning electrochemical imaging based on deconvolution.We analyses the problems and constructs a model according to trailing phenomenon,then we use the presented algorithm to solve the problem.In this paper,SECM-A and cyclic voltammetry are used to collect data from 8 sets of electrochemical experiments and form a set of data that can be processed.Then we analyze the data and speculate that the non chemical cause of the tail phenomenon of scanning electrochemical imaging is the charge convolution phenomenon caused by the disturbance of sampling rods.Then we use the de trailing algorithm proposed in this paper to process the collected 8 sets of data and display them.Finally,the imaging effect of raw data,shifted data and deconvolution data is compared,and then we use bilinear interpolation to process deconvolution data,the imaging results are also shown in this paper.By comparing the imaging results of the original data,the shift data and the deconvolution data,we can find that the data processed by the de trailing algorithm based on deconvolution is better than the displaced trailing method both in the improvement of the image trailing and the restoration of the whole image.Compared with original data,it not only greatly improves the influence of trailing phenomenon on whole imaging,but also improves blurry details and reduce the damage to details.
