扫描探针显微镜中数据格式的分析及转换程序的设计

Standardization and transform of SPM data formats

随着扫描探针显微镜技术发展和广泛应用,扫描探针显微镜的技术标准化问题在国内外受到越来越多的关注。然而在数据格式方面,由于所用硬件平台的不同等原因,各制造商所生产的扫描探针显微镜大多使用专用的数据格式。这些数据格式又往往互不兼容,给数据后续的分析处理和交流共享带来不便。本文首先对扫描探针显微镜中数据格式的发展及应用较多的格式进行了分析,然后从扫描探针显微镜现有数据的类型、内容和特点出发,研究了规范扫描探针显微镜数据格式的基本要求和思路;经过比较和筛选提出了一种基于HDF5标准(hierarchical data format,HDF)的标准格式方案;并用C++语言实现了对该格式的操作及其与几种专用数据格式之间的相互转换,完成了格式方案和代码资源的开源共享。

Standardization of SPM（scanning probe microscope） is drawing more and more attention nowadays.Most data formats in SPM are not compatible to each other,leading to the inconvenience of their subsequent analysis,processing and sharing.It is necessary to establish an open data format which has good compatibility and scalability.This paper analyzed the development of SPM data formats and some typical formats,and studied its standardization.Based on HDF5（hierarchical data format,HDF）,a solution for the standardization was given.A realization with C＋ ＋ programming language was demonstrated.The solution and all related codes were published via internet,which were available and free to anybody.
