|Title:||Digital phase-shifting shearography for slope measurement||Authors:||He, Y.M.
|Issue Date:||1999||Citation:||He, Y.M., Tay, C.J., Shang, H.M. (1999). Digital phase-shifting shearography for slope measurement. Optical Engineering 38 (9) : 1586-1590. ScholarBank@NUS Repository. https://doi.org/10.1117/1.602211||Abstract:||An electronic speckle shearing interferometry method for the full field measurement of the slope of an object is presented. The object under study is placed on a rotating platform and illuminated by an expanded laser beam. Its image is recorded by a shearing CCD camera and stored directly into a computer. By recording two images before and after giving the object a small angle of rotation, the resulting correlation fringe pattern that represents the object surface slope can be obtained. The theory of the new method and some experimental results are presented.||Source Title:||Optical Engineering||URI:||http://scholarbank.nus.edu.sg/handle/10635/58110||ISSN:||00913286||DOI:||10.1117/1.602211|
