Quiroga Mellado, Juan AntonioServín Guirado, Manuel2023-06-202023-06-202001-030950-034010.1080/09500340108230929https://hdl.handle.net/20.500.14352/58787© 2001 Taylor and Francis Ltd.In this work we propose a robust fringe demodulation technique applied to the analysis of a single isochromatics fringe pattern produced in photoelasticity. The method used is a regularized phase tracking algorithm with a new sequential scanning technique specifically adapted for the characteristics of the isochromatic fringe patterns: possible apparition of closed fringes, large dynamic range in its spatial frequency content and low noise. The performance of the method is discussed and experimental results are presented.journal articlehttp://dx.doi.org/10.1080/09500340108230929http://www.tandfonline.commetadata only access535OpticsÓptica (Física)2209.19 Óptica Física
