This work was partially supported by (Tecnologías Avanzadas de la Producción under project TAP92-0087 from the Comisión Interministerial de Ciencia y Tecnología).A new algorithm for phase unwrapping of phase maps with noise or logical inconsistencies is proposed. It is based on the use of an adaptive threshold and the second difference of the locally unwrapped phase as a selection criterion for the pixels to be processed.engjournal articlehttp://dx.doi.org/10.1364/AO.34.002560http://www.opticsinfobase.org/open access535Phase UnwrappingFringe-Pattern ProcessingÓptica (Física)2209.19 Óptica Física
