This article is dedicated to Professor Cesar Sciammarella

Shearography is a non-destructive testing technique. It can measure six surface strains when an object is subjected to an external agency. The paper reviews methods that are used to measure more than one strain simultaneously or sequentially. Also, it contains information on methods that combine shearography with speckle interferometry to yield information about deformation as well as its derivative. © Anita Publications.
