摘　　要：为了达到将MATLAB数据图像计算能力强大的特点与VB(Visual Basic)编程软件简单方便、界面可视的特点相结合的目的,采用组件对象模型(component object model,COM)技术在VB中调用MATLAB生成动态链接库的方法,将COM组件技术应用于数字全息中研究水中物体运动。结果表明,两者的结合可以减少设计编程时间,使得参量修改方便且可移植性强,从而可提高全息图像后续处理的效率和效果,具有一定的应用价值。以数字全息测量液体中蔗糖颗粒的运动为例,将混合编程处理结果与理论分析进行了对比,验证了该方法的可行性和准确性,具有一定的理论价值。MATLAB with powerful ability of the data and image processing and software Visual Basic （VB） with simple programming and visualization were combined and dynamic link library （DLL） technology which formed using the component object model（COM） component of MATLAB in VB software interface was used in digital holographic processing. It is shown that this can reduce the programming time, and it is convenient and easy to modify parameters. Furthermore the efficiency of the holographic image post-processing is improved so that the results, such as velocity and position of moving particles in reconstruction image can be obtained rapidly, and the developed method is of practical significance.
