摘　　要：介绍基于交流的电容层析成像系统软件设计和应用。采用VisualC++语言,基于Windows98和XP操作系统,首次开发编写了32位电容采集应用程序。软件可以应用于圆形和方形电容传感器,并能够应用于双层电容传感器,用于相关速度测量。软件还能够用于不同数目的电极传感器。系统的激励电压、频率、相位角均能够通过软件来实现。三种成像方法:LBP、Landweber和优化迭代方法嵌入到软件中。软件系统具有友好的界面,操作方面的特点。The software design for the AC-based ECT system is described. The first Windows 32-bit code for the system is written in Microsoft Visual C＋ ＋ ,working under Windows 98 and XP. It can operate the ECT system with a single-plane sensor,a dual-plane sensor and combined-electrodes. The software supports sensors with any number of electrodes and different shape ,square and circular. The amplitude, frequency and phase of the excitation and reference signals can be programmed. Three image reconstruction algorithms have been implemented,i.e. LBP,Landweber iteration and prior iteration. The software is easy to be operated and provides a user-friendly interface.
