用相对条纹级数法解释全息干涉图的误差统计分析

The errors' statistical analysis of the technique to interpret holographic interferograms using relative-fringe order method

本文对一种新的全息干涉图解释技术——相对条纹级数法进行了位移测量误差的统计分析,指出了减小误差的途径,并用实验验证了分析结果的正确性。分析表明,相对条纹级数法是一种功能较强的解释技术。

The statistical analysis of displacement measurement errors for the new technique to interpret holographic interferograms which is defined as relative -fringe order method is presented in this paper.The ways to reduce errors are given. The experimental results coincide with the theory. It is shown that relative-fringe order method is a powerful interpretation technique.
