摘要
提出了Ｆａｂｒｙ－Ｐｅｒｏｔ干涉条纹在变形情况下中心小数序的计算方法，分析了变形对计算结果的影响．在干涉图的数字化处理中对实验数据进行修正，提高了计算结果的精度，并给出了实验证明。根据计算出的系数，用计算机模拟的干涉图与实际拍摄的干涉图吻合。
The method for calculating the central fractional order of Fabry-Perot interference fringes in case of distertion is proposed.The effect of distortion on calculated result is analyzed.The precision is enhanced by revising measured data in the process of interference pattern digitization.It is proved that the interference pattern simulated by computer in terms of calculated coefficient corresponds with the practical in terference pattern recorded photographically.
