Here, we introduce a new phase unwrapping approach for noisy wrapped phase maps of continuous objects to improve the accuracy and computational time requirements of phase unwrapping using a rotational compensator (RC) method. The proposed algorithm is based on compensating the singularity of discontinuity sources. It uses direct compensation for adjoining singular point (SP) pairs and uses RC for other SP pairs. The performance of the proposed method is tested through both simulated and real wrapped phase data. The proposed algorithm is faster than the original algorithm with the RC and has proved efficiency compared to other phase unwrapping methods.Optical Society of AmericaJournal Articleapplication/pdfhttp://hdl.handle.net/2115/48197https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/48197/1/AO50-33_6225-6233.pdf0003-6935Applied Optics5033622562332011-11-20enginfo:pmid/22108880info:doi/10.1364/AO.50.006225© 2011 Optical Society of Americapublisher
