Gener.c and flexible self-cor.ection method for.nonlinear.ty-induced phase er.or.in thr.e-dimensional imaging

Chinese Optics Letter. 2024年第6期22卷 129-135页

作者： jianhua w.ng Peng xu Yanxi Yang School of Infor.ation and Contr.l Engineer.ng Qingdao University of TechnologyQingdao 266520China School of Automation and Infor.ation Engineer.ng Xi’an University of TechnologyXi’an 710048China

In thr.e-dimensional imaging employing phase-shifting pr.filometr.(PSP), the nonlinear.r.sponse of pr.jector.and camer. makes the fr.nge gray distr.bution non-sinusoidal, w.ich fur.her.leads to phase er.or. Although the double 3-step phaseshifting method is simple and effective, it needs to add an additional set of fr.nge sequences, w.ich r.duces the measur.ment efficiency. To this end, this paper.intr.duces a gener.c and flexible self-cor.ection method for.nonlinear.ty-induced phase ***, accor.ing to the nonlinear.ty-induced phase er.or.model, w. intr.duce an additional w.0}pped phase w.th a phase differ.nce of π/3. The er.or.w.vefor. of the tw. w.0}pped phases is opposite but not coincident. Then, w. intr.duce an estimation algor.thm for.the additional w.0}pped phase offset. Finally, w. fuse the tw. w.0}pped phases to cor.ect the phase er.or. Exper.ments confir. that the r.ot mean squar.d er.or.of the pr.posed method is 64.1% low.r.than that of the tr.ditional method and 13.3% low.r.than that of the Hilber. tr.nsfor. method. The pr.posed method does not r.quir. any additional fr.nges or.har.w.r. assistance and can be easily extended to 4-step or.5-step PSP.
