相位解包裹中欠采样问题的实验研究
Experimental study about undersampling phase unwrapping
摘要
Abstract
In order to solve the undersampling problem of phase unwrapping caused by fast changing of phase , the theory of lateral shearing interferometry was introduced to build optical field and weighted discrete cosine transform was used to solve Poisson equation.On this basis, a new improved least square algorithm based on lateral shearing interferometry ( LSBLS) algorithm was put forward .The specific phase unwrapping method was given based on theoretical analysis and the feasibility of the improved algorithm was proved after experimental verification .The results show that the improved algorithm can effectively avoid the undersampling problem caused by the fast changing of phase .关键词
