用光学干涉计量方法获得光场相位,通常都需要做去噪运算。在光场相位空间变化频率不高的情况下,目前的各种算法都能取得不错的效果。如果光场相位空间变化剧烈,传统去噪算法常引起细节丢失、条纹断裂。针对这个问题,通过引入光场的横向剪切,显著降低光场相位的空间变化频率,从而将噪声从光场中分离出来。给出了一种新的去噪算法和相应的理论分析,通过模拟计算和实验验证,证明该算法是可行和有效的,在光场相位空间变化频率较高的情况下,能得到比传统去噪算法更好的结果。 Optical interferometry method to obtain the phase of the light field, usually need to do denoising operation. In the light field phase space frequency is not high, the current various algorithms can achieve good results. If the phase space of the light field changes dramatically, the traditional denoising algorithm often causes the details to be lost and the stripe to rupture. In response to this problem, the noise is separated from the light field by introducing transverse shear of the light field, which significantly reduces the spatial frequency of the phase of the light field. A new denoising algorithm and corresponding theoretical analysis are given. It is proved that the algorithm is feasible and effective by simulation and experiment. Under the condition of high spatial frequency of the optical field, Noise algorithm for better results.
