摘　　要：干涉条纹计数实验软件可自动完成光学实验中干涉条纹的自动采集和移动条纹计数。该系统利用PCI高速的数据采集与传输特性,实现干涉图像的采集,运用图像的处理算法实现条纹的识别和定位。本系统融合了图像处理不同阶段的多种算法,取得较好的效果。克服了光学实验中依靠人眼直接判读干涉条纹的种种缺陷,实时跟踪移动的条纹及自动计数,便于学生完成干涉条纹进行测量物理量的实验。The experimental software for connting interference fringes could accomplish the auto：sampling and counting moving fringes. The software accomplishes sampling interference video through PCI high-speed capacity of data sampling and transmitting, and exerts the digital image algorithms to identify and locate the fringes. The software combines with many algorithms in various stages, achieves better effect. It could overcome many disadvantages which survive in manual watching and measuring interference fringes in optical experiments, and could trace moving fringes in real time and auto-count the fringes,could facilitate students to accomplish experiments that measure some physicalquantities by the laser interference fringes.
