Branch cutting algorithm for unwrapping photoelastic phase map with isotropic point

Publication year: 2011 Source: Optics and Lasers in Engineering, Available online 21 December 2011 Yao-Ting Zhang, Min-Jui Huang, Hua-Rong Liang, Fu-You Lao A branch cutting algorithm is proposed to solve the wrapped isoclinic causing isochromatic discontinuity and thus to decouple the isoclinic–isochromatic interaction of photoelastic phase maps. Rather than pixel by pixel, the branch-cutting isoclinic wrapped map is then restored by a modified regional approach and is proved to be more time-effective and less effort needed than the author’s earlier algorithm. The decoupled isochromatic data can be handled easily afterward
