| 摘 要： | 为减小在动态干涉条纹的相位提取中噪声带来的计数误差，研究了在希尔伯特变换相位提取的基础上，利用反正切相位跳变特性，通过软件实现可逆计数的抗干扰算法。通过模拟实验对算法的抗干扰性能进行了验证，实验结果表明：所提出的相位提取算法具有较强的抗干扰性能，在信噪比为11时，算法仍然能得到正确的结果。

| Abstract: | In order to reduce the error counts with high noise in the phase extracting of dynamic interference fringes, based on the phase extracting method with Hilbert transform, an anti-jamming algorithm with reversible counting using the arctan gent phase characteristic was presented. The experiment results show that the algorithm can greatly increase the anti-jamming performance of phase extracting, there is an accurate result when the signal to noise ratio equals 11. |
