相位展开在许多基于相位信息的数据处理链中仍然起着重要的作用。在这里，我们介绍了一种新的相位展开方法，用于连续对象的噪声包裹相位图，以提高相位展开的精度和计算时间要求，使用旋转补偿器（RC）方法。该算法是基于补偿的奇异性不连续源。它使用直接补偿相邻的奇异点（SP）对，并使用RC的其他SP对。通过仿真和真实的包裹相位数据对所提方法的性能进行了测试。该算法的速度比原算法与RC和已被证明的效率相比，其他相位展开方法。
Phase unwrapping still plays an important role in many data-processing chains based on phase information. Here, we introduce a new phase unwrapping approach for noisy wrapped phase maps of continuous objects to improve the accuracy and computational time requirements of phase unwrapping using a rotational compensator (RC) method. The proposed algorithm is based on compensating the singularity of discontinuity sources. It uses direct compensation for adjoining singular point (SP) pairs and uses RC for other SP pairs. The performance of the proposed method is tested through both simulated and real wrapped phase data. The proposed algorithm is faster than the original algorithm with the RC and has proved efficiency compared to other phase unwrapping methods.
