由于不可预知影响因素的存在,使得相位的正确展开成为一个非常困难的问题,为了更好地指导相位正确展开,对几种经典的质量权值进行了详细的分析。给出了它们的完整的数学描述,然后基于数学模型进行了详细的原理性推导,分析各种质量权值的性能和特点,并根据其物理意义在同领域或相关领域提出了新的改进算法,最后,通过实例验证了改进算法的正确性和优越性,同时也证明了该分析对理解和研究相位展开的普遍指导意义。
Due to the unpredictable influence factors, the correct development of the phase becomes a very difficult problem. In order to better guide the correct phase expansion, several classical mass weights are analyzed in detail. Gives their complete mathematical description, and then carries on the detailed principle derivation based on the mathematical model, analyzes the performance and the characteristic of various quality weights, and proposes new improved algorithms in the same field or related fields according to their physical meaning Finally, the correctness and superiority of the improved algorithm are verified by an example. At the same time, it also proves the general guiding significance of this analysis to understand and study phase unwrapping.
