条纹分析作为一种精密测量技术在工程领域得到了广泛的应用。本文讨论了一种提高空间条纹分析精度的方法。提出了一种基于条纹扫描和插值技术的新方法。提出了基于该方法的二维条纹分析方法。用新的二维方法得到的测量结果和用FFT方法得到的测量结果进行了比较。结果表明，在精度相当的情况下，新方法的计算时间是FFT方法的5倍。
Fringe analysis is used in engineering fields as a precise measurement technology. In this paper, a method for improving the accuracy of spatial fringe analysis is discussed. A new method, based on fringe scanning and interpolation techniques, is put forward. Two-dimensional fringe analysis based on this new method is also proposed. Measured results obtained using the new two-dimensional method and those obtained using the FFT method are compared. Results showed that while the accuracy of the two methods is equivalent, the calculation time for the new method is five times as speedy as that for the FFT method.
