中文摘要：

为满足动态数字全息的实时、在线检测分析的需求,提出了一种应用于动态数字全息的快速相位解包裹算法。在充分考虑相位解包裹的精确性和运行时间的基础上,首先找出影响解包裹精确性的坏点,并进行标记;采用运行速度较快的中心点辐射解包裹算法,使解包裹路径避开这些坏点,并利用动态全息相位图在时域上的关联;在时域上设置解包裹路径,以解决不同帧的相位值在时域上的关联问题和坏点封闭区域的相位解包裹问题。实验结果表明,本文算法是合理和有效的,运行速度较快,解包裹的精确性较高。

英文摘要：

Based on the requirement for real-time,online detection and analysis of dynamic digital holography,in this paper,a fast phase unwrapping algorithm used in dynamic digital holography is presented.We find out the inaccurate points affecting unwrapping accuracy while fully considering phase unwrapping accuracy and running time,make some marks for them,and then use the center radiation phase unwrapping algorithm,which has relatively fast operating speeds to bypass these inaccurate points.In order to solve the relevance problem in time domain for phase values of different frames and the phase unwrapping problem for inaccurate points enclosed area,we use the relevance in time domain of dynamic digital holograms after setting the unwrapping path in time domain.Experimental results show that this algorithm is reasonable and effective.It has a fast speed and high accuracy in phase unwrapping.
