摘要
本文针对光干涉条纹图的特点,以近年来采用的多种方法为基础,找出了提取条纹中心线的“探索数”算法。分析和实验表明,该算法实现速度快,处理精度好,自动化程度高。本文介绍了该算法处理云纹图和全息图的实例。
The exploring—number algorithm of extracting the fringe centre line to the opti- cal interferometric patterns,based on the normal methods in recent years,is presented in this paper.By analysing and experimenting,we can say that the algorithm is precise and automatic, and processes the patterns at fast speed.Lastly,this paper introduces the experimental examples of Moire and holographic pattern.
