Quantitative Study of Deformations using Electronic Speckle Pattern Interferometer (ESPI)By P.P. Padghan, K.M. Alti
Abstract: AbstractThis paper discusses a research proposal to use temporal phase shifting technique of Electronic Speckle Pattern Interferometer (ESPI) for qualitative and quantitative study of deformations of various kinds. Proposed method for quantitative study is a five step phase shifting algorithm for extraction of phase information from the deformed object. Mechanical and thermal deformations in metallic thin films, metal plates and acoustic deformations are been planned for the study.Keywords: Temporal phase …
