ScholarBank@NUS Repository. https://doi.org/10.1364/AO.47.002874 | Abstract: | Measurement of curvature and twist is an important aspect in the study of object deformation. In recent years, several methods have been proposed to determine curvature and twist of a deformed object using digital shearography. Here we propose a novel method to determine the curvature and twist of a deformed object using digital holography and a complex phasor. A sine/cosine transformation method and two-dimensional short time Fourier transform are proposed subsequently to process the wrapped phase maps. It is shown that high-quality phase maps corresponding to curvature and twist can be obtained. An experiment is conducted to demonstrate the validity of the proposed method. © 2008 Optical Society of America. | Source Title: | Applied Optics | URI: | http://scholarbank.nus.edu.sg/handle/10635/60695 | ISSN: | 00036935 | DOI: | 10.1364/AO.47.002874 |
