|Title:||A real-time digital shearing speckle interferometer||Authors:||Chau, F.S.
|Issue Date:||1992||Citation:||Chau, F.S., Ng, T.W. (1992). A real-time digital shearing speckle interferometer. Measurement Science and Technology 3 (4) : 381-383. ScholarBank@NUS Repository. https://doi.org/10.1088/0957-0233/3/4/008||Abstract:||Shearography is an interferometric method which measures surface displacement derivatives. Although useful for strain analysis and non-destructive testing, the conventional technique is cumbersome and not very suitable for an industrial environment. The authors present the development of an electronic/digital technique which eliminates most of the shortcomings. It enables real-time shearographic fringes to be obtained.||Source Title:||Measurement Science and Technology||URI:||http://scholarbank.nus.edu.sg/handle/10635/54769||ISSN:||09570233||DOI:||10.1088/0957-0233/3/4/008|
