数字图像处理技术在扫描电化学显微镜中的应用
Application of Digital Image Processing Technology in Scanning Electrochemical Microscope
摘要
Abstract
Ultramicroelectrode was usually used in scanning electrochemical microscope(SECM) as a probe. The redox reaction on the probe is a diffusion process. But the fast moving of probe in SECM will affect the diffusion process, resulting in unclear obtained images. A new SECM image-processing technique was proposed in this paper involving combination of LoG algorithm and New edge-directed interpolation (NEDI) interpolation algorithm. LoG algorithm is helpful for the clarity of SECM images, but leading to some loss of edge information. Fortunately, NEDI algorithm based on edge directed interpolation can solve this problem well. Two substrates with gold interdigitated electrode and gold electrode array were prepared by ion sputtering method. The SECM images were obtained of the gold interdigitated electrode, gold electrode array and ITO substrate printed with fingerprints. The corresponding images treated by LoG filter and these for NEDI interpolation were compared and analyzed. The image-processing technique combining the LoG algorithm with the NEDI interpolation algorithm can significantly improve the clarity and resolution of SECM image.关键词
