介绍了一种利用软件基本上代替硬件实现干涉条纹可逆计数的方法。从可逆计数的基本要求出发，文章描述了本方法的基本原理、信号处理，以及用软件买现的方法，并给出了程序流程图。对这种方法的实验验证表明，结果比较满意。
A method of reversible counting of interference fringes by using software instead of hardware is introduced. Starting from the basic requirements of reversible counting, this paper describes the basic principles of the method, signal processing, and the method of buying and selling software, and gives the program flow chart. Experimental verification of this method shows that the results are satisfactory.
