Wrap reduction algorithm for fringe projection profilometry [PDF]
Optics and Lasers in Engineering, 2022 Carrier removal has been typically associated with wrap reduction, and its application has strongly been recommended as a previous step to phase unwrapping. In general, the carrier signal contributes to an increase of the number of wraps, and its removal leads to a reduction of the number of phase inconsistencies, having a positive impact on the ...
